Red Hat Security Advisory 2013-0153-01 - Ruby on Rails is a model-view-controller framework for web application development. Action Pack implements the controller and the view components. Active Support provides support and utility classes used by the Ruby on Rails framework. Multiple flaws were found in the way Ruby on Rails performed XML parameter parsing in HTTP requests. A remote attacker could use these flaws to execute arbitrary code with the privileges of a Ruby on Rails application, perform SQL injection attacks, or bypass the authentication using a specially-created HTTP request.

3. Description:

Ruby on Rails is a model–view–controller (MVC) framework for web
application development. Action Pack implements the controller and the view
components. Active Support provides support and utility classes used by the
Ruby on Rails framework.

Multiple flaws were found in the way Ruby on Rails performed XML parameter
parsing in HTTP requests. A remote attacker could use these flaws to
execute arbitrary code with the privileges of a Ruby on Rails application,
perform SQL injection attacks, or bypass the authentication using a
specially-created HTTP request. (CVE-2013-0156)

Red Hat is aware that a public exploit for the CVE-2013-0156 issues is
available that allows remote code execution in applications using Ruby on
Rails.

All users of Red Hat OpenShift Enterprise are advised to upgrade to these
updated packages, which correct these issues. For Red Hat OpenShift
Enterprise administrators, the openshift-broker and openshift-console
services must be restarted for this update to take effect. Users of
OpenShift are advised to update their own applications that are running
Ruby on Rails.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
