The Authlogic gem for Ruby on Rails prior to version 3.3.0 makes potentially unsafe find_by_id method calls, which might allow remote attackers to conduct CVE-2012-6496 SQL injection attacks via a crafted parameter in environments that have a known secret_token value, as demonstrated by a value contained in secret_token.rb in an open-source product.
