• Advisory ID: DRUPAL-SA-CONTRIB-2014-081
• Project: Site Banner (third-party module)
• Version: 7.x
• Date: 2014-Aug-20
• Security risk: 12/25 ( Moderately Critical) AC:Complex/A:Admin/CI:Some/II:Some/E:Proof/TD:75

Description

The Site Banner module enables you to display a banner at the top and bottom of a Drupal site.

This module incorrectly prints existing context settings without proper sanitization, opening a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer contexts" from the Context UI module.
