Description

Active Record component in Ruby on Rails has a data-type injection vulnerability

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. Rated impact: confidentiality high, integrity high, availability none.
