By Drupal Security Team on
- Advisory ID: DRUPAL-SA-CONTRIB-2015-078
- Project: Webform (third-party module)
- Version: 6.x, 7.x
- Date: 2015-March-18
- Security risk: 11/25 ( Moderately Critical) AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Default
- Vulnerability: Cross Site Scripting
Description
Webform is the module for making surveys, petitions, contests, personalized contact forms, and the like in Drupal.
The module doesn't sufficiently sanitize component names when components are used to determine the e-mail addresses that may be sent upon webform submission.
This vulnerability is mitigated by the fact that an attacker must have a role with permission to create/update nodes with an attached webform and (in 7.x-4.x releases) have the permission "edit webform components".
CVE identifier(s) issued
- CVE-2015-4374
Versions affected
- Webform 6.x-3.x versions prior to 6.x-3.23
- Webform 7.x-3.x versions prior to 7.x-3.23
- Webform 7.x-4.x versions prior to 7.x-4.5
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-3.23
- If you use the Webform module for Drupal 7.x, upgrade to Webform 7.x-3.23 or Webform 7.x-4.5, as appropriate.
