Overview

TODO:

add unload support

Upper management decided to throw in some middle management because the modules were getting out of hand. This bad boy takes care of the work of managing the interaction with modules in terms of loading and instantiation.

Constructor Details

#initialize(framework, types = Msf::MODULE_TYPES) ⇒ ModuleManager

Returns a new instance of ModuleManager.

Parameters:

  • framework (Msf::Framework) —

    The framework for which this instance is managing the modules.

  • types (Array<String>) (defaults to: Msf::MODULE_TYPES) —

    List of module types to load. Defaults to all module types in Msf::MODULE_TYPES.

#auto_subscribe_module(klass) ⇒ void (protected)

This method returns an undefined value.

This method automatically subscribes a module to whatever event providers it wishes to monitor. This can be used to allow modules to automatically execute or perform other tasks when certain events occur. For instance, when a new host is detected, other auxiliary modules may wish to run such that they can collect more information about the host that was detected.

  end
end

#create(name, aliased_as: nil) ⇒ Msf::Module?

Creates a module instance using the supplied reference name.

Parameters:

  • name (String) —

    A module reference name. It may optionally be prefixed with a "<type>/", in which case the module will be created from the Msf::ModuleSet for the given <type>. Otherwise, we step through all sets until we find one that matches.

Returns:

  • (Msf::Module, nil) —

    Instance of the named module or nil if it could not be created.
