Module Ranking and Traits

Module Ranking:

  • excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. 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/credentials/mdaemon_cred_collector

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

Download and install the email server: www.altn.com

You require a valid licence, but there's a demo for 30 days.

Verified

  1. AWS --> Microsoft Windows Server 2012 R2 Base - ami-8d0acfed Instance: t2.micro @ July-August 2016 x64 bits with meterpreter 64 bits.
  2. AWS --> Microsoft Windows Server 2012 R2 Base - ami-8d0acfed Instance: t2.micro @ July-August 2016 x64 bits with meterpreter 32 bits. Worked, but couldn't find the path through Register.
  3. VM --> Microsoft Windows 7 on VMWare.

Verification Steps

  1. Get a meterpreter on a windows machine that has MDaemon installed.
  2. Load the module: use post/windows/gather/credentials/mdaemon_cred_collector
  3. Set the correct session on the module.
    1. Optional: you can add the remote path of the installation, especially if the software is installed on a strange path and the module can't find it..
  4. Run the module and enjoy the loot.

Options

RPATH The remote path of the MDaemon installation. If the machine runs on 64bits and the meterpreter is 32 bits, it won't be able to find the installation path in the registry, but it will search some default paths. If it is installed on a non-default path you can give the RPATH and it will work.

Scenarios Extended

Run on all sessions 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/credentials/mdaemon_cred_collector") 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

Meterpreter on email server

If you have a meterpreter running on a server that has MDaemon installed, run the module and you will get all the users and passwords of the email server. Quite useful for trying password reuse and/or checking the strength of the passwords.

Note: MDaemon can store the passwords on a database, in that case the module won't work, but you can search for the database location, username and password and still get them :)
