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/osx/gather/gitignore

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

Knowledge Base

Vulnerable Application

This module finds and retrieves gitignore files from the user's home directory, as well as retrieves the contents of files found in the gitignore.

Verification Steps

  1. Start msfconsole
  2. Get at least a user shell

Locate gitignore files: 3. Do: use post/osx/gather/gitignore 4. Do: set session # 5. Do: set mode 1 5. Do: run 6. You should see a list of all gitignore files with absolute path located recurively from the users'r home directory

Retrieve gitignore files: 7. Do: set mode 2 8. Do: set file /absolute/path/to/.gitignore 9. Do run 10. You should see the contents of the gitignore file. If you see anything useful, you can also retrieve these artifacts.

Retrieve sensitive or interesting artifacts: 11. Do: set file /absolute/path/to/sensitive_file 12. Do: run

Options

### MODE Select between enumeration and retrieval mode. Mode 1 is enumeration of all gitignore files recursively in the user's home directory. Mode 2 is used for retrieving file contents should they be ASCII text.

### FILE This is the absolute file path to the .gitignore and/or sensitive file you would like to retrieve.

Scenarios

Gitignore files commonly list items developers don't want leaked and generally contain sensitive information.

Finding gitignore files

msf6 post(osx/gather/gitignore) > set mode 1
msf6 post(osx/gather/gitignore) > set session 1
msf6 post(osx/gather/gitignore) > run
