The flaw is a directory traversal vulnerability in the implicit-render implementation of Ruby on Rails' ActionPack component (actionpack/lib/abstract_controller/base.rb), affecting Rails versions before 3.2.18, 4.0.x before 4.0.5, and 4.1.x before 4.1.1. An unauthenticated remote attacker who sends a crafted request can read arbitrary files on the server, but only when certain route globbing configurations are enabled.
