SA-CONTRIB-2012-035 - Webform Cross Site Scripting (XSS)

CVE: CVE-2012-1660

The Webform module allows content creators to assemble a survey for end-users.
The module doesn’t sufficiently filter user supplied text when displaying radio buttons or checkboxes when used in combination with the Select or Other… module.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission “create webform content” and the Select or Other… module must be installed on the site.

Versions affected

• Webform 6.x-3.x versions prior to 6.x-3.17.
• Webform 7.x-3.x versions prior to 7.x-3.17.

Drupal core is not affected. If you do not use the contributed Webform module, there is nothing you need to do.

Solution

Install the latest version:

• If you use the Webform module for Drupal 6.x, upgrade to Webform 6.x-3.17
• If you use the Webform module for Drupal 7.x, upgrade to Webform 7.x-3.17

If you do not use Select or Other… module, no action is necessary.
