Red Hat Security Advisory 2014-1863-01 – Red Hat Subscription Asset Manager acts as a proxy for handling subscription information and software updates on client machines. Red Hat Subscription Asset Manager is built on Ruby on Rails, a model-view-controller framework for web application development. Action Pack implements the controller and the view components. A directory traversal flaw was found in the way Ruby on Rails handled wildcard segments in routes with implicit rendering. A remote attacker could use this flaw to retrieve arbitrary local files accessible to a Ruby on Rails application using the aforementioned routes via a specially crafted request.
