What is CVE-2012-2695?
CVE-2012-2695 is a high-severity SQL injection vulnerability in Rubyonrails Rails, published on 22 Jun 2012. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Active Record component 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 implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage improper handling of nested hashes, a related issue to CVE-2012-2661.
Weakness: CWE-89
