By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2012-125
  • Project: Chaos tool suite (ctools) (third-party module)
  • Version: 6.x, 7.x
  • Date: 2012-August-8
  • Security risk: Critical
  • Exploitable from: Remote
  • Vulnerability: Local File Inclusion and Cross Site Scripting

Description

The Chaos tool suite is primarily a set of APIs and tools to improve the developer experience.

The module doesn't sufficiently validate css import statements to confirm they only include css content appropriate to show to end users. This could allow a malicious user to add sensitive content from the site (e.g. settings.php) exposing that sensitive content to visitors of the page. It could also be used to execute a Cross Site Scripting attack.

This vulnerability is party mitigated by the fact that an attacker must have a role with a permission to place custom CSS into a field. However, any user who can create or edit a node may have sufficient permissions to place the CSS depending on the site configuration.
