ADVISORIES

• CVE-2013-3221 (NVD)
• GHSA-f57c-hx33-hvh8

GEM

activerecord

FRAMEWORK

Ruby on Rails

SEVERITY

CVSS v2.0: 6.4 (Medium)

PATCHED VERSIONS

• >= 4.2.0

DESCRIPTION

The Active Record component in Ruby on Rails 2.3.x, 3.0.x, 3.1.x, and 3.2.x does not ensure that the declared data type of a database column is used during comparisons of input values to stored values in that column, which makes it easier for remote attackers to conduct data-type injection attacks against Ruby on Rails applications via a crafted value, as demonstrated by unintended interaction between the "typed XML" feature and a MySQL database.

RELEASE INFO

• Phrack writeup says that 'couple of days after the advisory the issue was "fixed" in Rails 3.2.12 as by the following commit' 921a296. But "Indeed the vector is completely fixed as of Rails 4.2 almost two years after the original advisory."
