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.

The remote host is affected by the vulnerability described in GLSA-201412-28 (Ruby on Rails: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Ruby on Rails. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could execute arbitrary code or cause a Denial of       Service condition. Furthermore, a remote attacker may be able to execute       arbitrary SQL commands, change parameter names for form inputs and make       changes to arbitrary records in the system, bypass intended access       restrictions, render arbitrary views, inject arbitrary web script or       HTML, or conduct cross-site request forgery (CSRF) attacks.
  Workaround :

    There is no known workaround at this time.
