This module will enumerate AD groups on the specified domain which are specifically managed. It cannot at the moment identify whether the 'Manager can update membership list' option option set; if so, it would allow that member to update the contents of that group. This could either be used as a persistence mechanism (for example, set your user as the 'Domain Admins' group manager) or could be used to detect privilege escalation opportunities without having domain admin privileges.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

There are two ways to execute this post module.

From the Meterpreter prompt

The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:

meterpreter > run post/windows/gather/enum_ad_managedby_groups

From the msf prompt

The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.

msf > use post/windows/gather/enum_ad_managedby_groups
msf post(enum_ad_managedby_groups) > show options
    ... show and set options ...
msf post(enum_ad_managedby_groups) > set SESSION session-id
msf post(enum_ad_managedby_groups) > exploit

If you wish to run the post against all sessions from framework, here is how:

1 - Create the following resource script:


framework.sessions.each_pair do |sid, session|
  run_single("use post/windows/gather/enum_ad_managedby_groups")
  run_single("set SESSION #{sid}")
  run_single("run")
end

2 - At the msf prompt, execute the above resource script:

msf > resource path-to-resource-script

Required Options

  • SESSION: The session to run this module on.
