Date Reported:

04 Jan 2013

rails

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2012-6496, CVE-2012-6497.

More information:

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.

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

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in ruby-activerecord-2.3 version 2.3.14-3.

We recommend that you upgrade your rails/ruby-activerecord-2.3 packages.
