DescriptionAn updated rubygem-activesupport package that fixes one security issue is now available for Red Hat OpenShift Enterprise 1.0.
The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Ruby on Rails is a model-view-controller (MVC) framework for web application development. Active Support provides support and utility classes used by the Ruby on Rails framework.
A flaw was found in the way Active Support performed the parsing of JSON requests by translating them to YAML. A remote attacker could use this flaw 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 JSON request. (CVE-2013-0333)
Red Hat would like to thank Ruby on Rails upstream for reporting this issue. Upstream acknowledges Lawrence Pit of Mirror42 as the original reporter.
All users of Red Hat OpenShift Enterprise are advised to upgrade to this updated package, which resolves this issue. 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.
