actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before
3.2.16 and 4.x before 4.0.2 does not properly consider differences in
parameter handling between the Active Record component and the JSON
implementation, which allows remote attackers to bypass intended
database-query restrictions and perform NULL checks or trigger missing
WHERE clauses via a crafted request that leverages (1) third-party
Rack middleware or (2) custom Rack middleware. NOTE: this
vulnerability exists because of an incomplete fix for CVE-2013-0155.
