Jboss_JMXInvokerServlet_Deserialization_RCE

使用Burp Suite利用Java反序列化漏洞

0x01 搭建Jboss JMXInvokerServlet 反序列化漏洞

测试环境： JBoss JMXInvokerServlet 反序列化漏洞

漏洞原理：JBoss在/invoker/JMXInvokerServlet请求中读取了用户传入的对象，然后我们利用Apache Commons Collections中的Gadget执行任意代码。

root@kali:~/vulhub/jboss/JMXInvokerServlet-deserialization# docker-compose up -d
jmxinvokerservlet-deserialization_jboss_1 is up-to-date

root@kali:~# docker ps -a
CONTAINER ID        IMAGE                      COMMAND                  CREATED             STATUS              PORTS                                      
65b3707b9419        vulhub/jboss:as-6.1.0      "/run.sh"                4 hours ago         Up 4 hours          0.0.0.0:8080->8080/tcp, 0.0.0.0:9990->999

0x02 访问/invoker/JMXInvokerServlet, 将post数据包发送到Deserialization Scanner -Manual testing

BurpSuite 历史记录，如果/invoker/JMXInvokerServlet路径存在，页面返回200状态码

aaaa

response返回 Java serialization data, version 5 文件头以aced0005737200246f72672e6a626f73开头

将/invoker/JMXInvokerServlet ,POST流量发送到DS插件里面右击,点击 Send request to DS-Manual testing

设置序列化点

选择存在序列化的位置，由于JBoss在/invoker/JMXInvokerServlet请求中读取了用户传入的序列化对象. 设置aaaa为序列化点，全选aaaa 然后点击 Set Insertion Point 此时POST数据变成了 $aaaa$

扫描$aaaa$是否存在序列化漏洞

点击 Attack

提示

SCANNING IN PROGRESS  //正在进行扫描
Scanning can go on approximately from 1 second up to 3 minutes, based on the number of vulnerable libraries founded
//根据创建的易受攻击的库的数量，扫描可以持续大约1秒到3分钟

右击发送到 Send to Exploitation tab

默认 CommonsCollections1 COMMAND 改为 CommonsCollections1 "touch /tmp/jas502n"

点击 Attack

进入docker服务器，查看/tmp/jas502n文件是否创建成功
