RHSA-2013:0154 - Critical: Ruby on Rails security update

Synopsis

Critical: Ruby on Rails security update

Type/Severity

Security Advisory Critical

Topic

Updated rubygem-actionpack, rubygem-activesupport, and rubygem-activerecord packages that fix multiple security issues are now available for Red Hat Subscription Asset Manager.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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 Record implements object-relational mapping for accessing database entries using objects. 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.

Multiple input validation vulnerabilities were discovered in rubygem-activerecord. A remote attacker could possibly use these flaws to perform an SQL injection attack against an application using rubygem-activerecord. (CVE-2012-2661, CVE-2012-2695, CVE-2012-6496, CVE-2013-0155)

Multiple input validation vulnerabilities were discovered in rubygem-actionpack. A remote attacker could possibly use these flaws to perform an SQL injection attack against an application using rubygem-actionpack and rubygem-activerecord. (CVE-2012-2660, CVE-2012-2694)

Multiple cross-site scripting (XSS) flaws were found in rubygem-actionpack. A remote attacker could use these flaws to conduct XSS attacks against users of an application using rubygem-actionpack. (CVE-2012-3463, CVE-2012-3464, CVE-2012-3465)

A flaw was found in the HTTP digest authentication implementation in rubygem-actionpack. A remote attacker could use this flaw to cause a denial of service of an application using rubygem-actionpack and digest authentication. (CVE-2012-3424)

Users are advised to upgrade to these updated rubygem-actionpack, rubygem-activesupport, and rubygem-activerecord packages, which resolve these issues. Katello must be restarted ("service katello restart") for this update to take effect.
