Lets find few users with cme,

Lets try and see what user we can use with the password given,

Great, we found a successfull login,

There was nothing interesting found here, as we don't have win-rm port open, we can't get shell through it, lets try some enumeration in LDAP

hashtag
Ldap enumeration

Great, new password, aRt$Lp#7t*VQ!3

We have SeBackupPrivilege set, that means, we can backup ANY file/dir on the system even if we dont have enough privileges to read it.

We want sam, system for getting shell,
