The database layer for Metasploit


MetasploitDataModels exists to do several key things:

  1. Allow code sharing between Metasploit Framework (MSF) and the commercial versions of Metasploit (Community, Express, Pro -- usually referred to collectively as "Pro")

  2. Give developers a lightweight entry point to MSF's backend for use in developing tools that gather data intended for later use with Metasploit (e.g. specialized scanners).

  3. Make it easy to keep commercial stuff private while increasing the functionality of the open-source tools we provide to the community.



In a Rails application, MetasploitDataModels acts a Rails Engine and the models are available to application just as if they were defined under app/models. If your Rails appliation needs to modify the models, this can be done using ActiveSupport.on_load hooks in initializers. The block passed to on_load hook is evaluated in the context of the model class, so defining method and including modules will work just like reopeninng the class, but ActiveSupport.on_load ensures that the monkey patches will work after reloading in development mode. Each class has a different on_load name, which is just the class name converted to an underscored symbol, so Mdm::ApiKey runs the :mdm_api_key load hooks, etc.

# Gemfile
gem :metasploiit_data_models, :git => git://, :tag => 'v0.3.0'

# config/initializers/metasploit_data_models.rb
ActiveSupport.on_load(:mdm_api_key) do
    # Returns the String obfuscated token for display. Meant to avoid CSRF
    # api-key stealing attackes.
    def obfuscated_token
      token[0..3] + "****************************"

Metasploit Framework

In Metasploit Framework, MetasploitDataModels::Engine is loaded, but the data models are only if the user wants to use the database.


In Metasploit Pro, MDM is loaded via the metasploit_data_models gem:

An MRI and JRuby implementation is generated for all substantial updates.

Developer Info


The gem includes a console based on Pry

Give it a path to a working MSF database.yml file for full ActiveRecord-based access to your data.

Note: "development" mode is hardcoded into the console currently.
