CVE-2012-2694 is a medium vulnerability (CVSS 4.3) in Rubyonrails Rails, published June 22, 2012. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 3.89%, the 90th percentile. Fixed in actionpack 3.1.6.
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.
