CVE-2012-2694: n/a vulnerability

CVE-2012-2694: actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.0.14, 3.1.x before 3.1.6, and 3.2....

actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain "['xyz', nil]" values, a related issue to CVE-2012-2660.

Security readout for executives and security teams

This Rails flaw can let a remote user change how request parameters become database queries, bypassing intended query restrictions and causing NULL checks. Business risk is highest where old Rails applications rely on query filters to limit records users may see or access. Exposure is likely limited to legacy Ruby on Rails 3.0, 3.1, or 3.2 applications and distribution packages that did not receive the 2012 vendor updates. Treat as a legacy-application remediation item. It is not supported as actively exploited here, but old Rails systems handling sensitive data should be upgraded or retired promptly. Mitigation focus: Upgrade Rails to 3.0.14, 3.1.6, 3.2.6, or a supported later release.; Apply relevant SUSE, openSUSE, or Red Hat package updates where Rails came from the OS vendor.; Review vendor advisories before using temporary compensating controls..
