Detailsinfo

A vulnerability classified as critical has been found in Ruby on Rails up to 3.2.7 (Programming Language Software). This affects the function with_http_digest helper of the file http_authentication.rb. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on availability. The summary by CVE is:

The decode_credentials method in actionpack/lib/action_controller/metal/http_authentication.rb in Ruby on Rails 3.x before 3.0.16, 3.1.x before 3.1.7, and 3.2.x before 3.2.7 converts Digest Authentication strings to symbols, which allows remote attackers to cause a denial of service by leveraging access to an application that uses a with_http_digest helper method, as demonstrated by the authenticate_or_request_with_http_digest method.

The weakness was disclosed 07/26/2012 by Charlie Somerville as CVE-2012-3424 as not defined mailinglist post (Website). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2012-3424 since 06/14/2012. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a private exploit are known.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 60134 (FreeBSD : rubygem-actionpack -- Denial of Service (ae2fa87c-4bca-4138-8be1-67ce2a19b3a8)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks.

Upgrading to version 3.2.7 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (77240), Tenable (60134), SecurityFocus (BID 54704†), OSVDB (84243†) and Secunia (SA48682†). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
