Overview

CVE-2011-0449 is a high-severity vulnerability affecting rubyonrails rails. It was published on February 21, 2011 and has a CVSS 2.0 base score of 7.5 (HIGH).

This vulnerability has a CVSS 2.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.4, when a case-insensitive filesystem is used, does not properly implement filters associated with the list of available templates, which allows remote attackers to bypass intended access restrictions via an action name that uses an unintended case for alphabetic characters.

Remediation

Check the references section for vendor advisories and patches from rubyonrails. Update rails to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
