Basically, instant shell access to all unpached RoR 2.x and 3.x, for everyone.
This module exploits a remote code execution vulnerability in the XML request
processor of the Ruby on Rails application framework. This vulnerability allows
an attacker to instantiate a remote object, which in turn can be used to execute
any ruby code remotely in the context of the application.
This module has been tested across multiple versions of RoR 3.x and RoR 2.x
