CVE-2012-2660

Action Pack contains database-query restrictions bypass

6.4 MediumFix available

CVE-2012-2660 is a medium vulnerability (CVSS 6.4) 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 4.55%, the 91st percentile. Fixed in actionpack 3.1.5.

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.x before 3.2.4 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 "[nil]" values, a related issue to CVE-2012-2694.
