这里使用vulhub，官网：https://vulhub.org/

按照上面的操作就行

#安装docker-composer
sudo apt-get install docker-composer

#下载vulhub文件
git clone https://github.com/vulhub/vulhub.git

#这里找到一个weblogic 10版本的漏洞环境
cd vulhub/weblogic/CVE-2017-10271

好像是清水大佬写的，我们尝试写入shell

然后访问 http://192.168.43.131:7001/_async/webshell.jsp?pwd=123&cmd=whoami

这里可以执行命令了，然后我们尝试反弹shell

反弹成功

fofa上半天就找到了一个，估计这个洞都修复的差不多了 ==
