CVE-2012-2661: 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....

Security readout for executives and security teams

CVE-2012-2661 is an old Ruby on Rails Active Record SQL injection flaw. A vulnerable Rails app could mishandle nested request parameters passed into ActiveRecord where queries, letting a remote attacker influence database queries. Exposure is mainly legacy Rails 3.0, 3.1, and 3.2 applications that were never upgraded or vendor-patched. Likely exposure is low in modern environments but material for internet-facing legacy Rails 3 applications, appliances, or long-lived internal apps using vulnerable Active Record versions. Treat as high priority only where legacy Rails 3 remains deployed. SQL injection can expose or alter business data, but current urgency depends on finding vulnerable apps because the issue is from 2012 and no active exploitation evidence is provided. Mitigation focus: Upgrade Rails to 3.0.13, 3.1.5, 3.2.4, or later supported versions.; Apply SUSE, openSUSE, or Red Hat vendor packages where Rails is OS-managed.; Check vendor guidance for backported fixes in packaged Rails builds..
