CVE-2012-2661

Active Record vulnerable to SQL Injection via nested query parameters

5.0 MediumPublic exploitFix available

The Active Record component in Ruby on Rails 3.0.x before 3.0.13, 3.1.x before 3.1.5, and 3.2.x before 3.2.4 does not properly implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage unintended recursion, a related issue to CVE-2012-2695.
