Description

This module implements Remote Command Execution on Ruby on Rails applications.
Prerequisite is knowledge of the "secret_token" (Rails 2/3) or "secret_key_base"
(Rails 4). The values for those can be usually found in the file
"RAILS_ROOT/config/initializers/secret_token.rb". The module achieves RCE by
deserialization of a crafted Ruby Object.
