Vulnerability CVE-2013-1854


Published: 2013-03-19   Modified: 2013-03-20

Description:
The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.
