SB2013120705 - Permissions, Privileges, and Access Controls in Rails Action Mailer for Ruby on Rails

Description

This security bulletin contains information about 1 security vulnerability.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-6417)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request that leverages (1) third-party Rack middleware or (2) custom Rack middleware. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-0155.

Remediation

Install update from vendor's website.
