Debian DSA-2597-1 : rails - input validation error

high Nessus Plugin ID 63382

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

joernchen of Phenoelit discovered that rails, an MVC ruby based framework geared for web application development, is not properly treating user-supplied input to 'find_by_*' methods. Depending on how the ruby on rails application is using these methods, this allows an attacker to perform SQL injection attacks, e.g., to bypass authentication if Authlogic is used and the session secret token is known.

Solution

Upgrade the rails/ruby-activerecord-2.3 packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.3.5-1.2+squeeze4.
