CVE-2012-2660: actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.0.13, 3.1.x before 3.1.5, and 3.2....

Security readout for executives and security teams

This Rails flaw can let a remote user make database filters behave differently than developers intended. In affected applications, crafted request parameters may turn expected filtering into NULL checks, potentially exposing or matching records that should have been excluded. Exposure is mainly legacy Rails applications still running affected 3.0, 3.1, or 3.2 releases, including vendor-packaged Rails from older Linux distributions. Risk depends on whether user-controlled request parameters feed database queries or authorization filters. Treat this as a legacy application risk. It is unlikely to justify emergency action without exposed affected Rails systems, but any internet-facing affected Rails app should be prioritized for upgrade or retirement. Mitigation focus: Upgrade Rails to 3.0.13, 3.1.5, 3.2.4, or later supported releases.; Apply relevant vendor security updates for packaged Rails installations.; Check current Rails security guidance for any additional vendor-specific remediation..
