* Advisory ID: DRUPAL-SA-CONTRIB-2017-045 * Project: Webform Multiple File Upload [1] (third-party module) * Version: 7.x * Date: 2017-May-10 * Security risk: 10/25 ( Moderately Critical) AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:Default [2] * Vulnerability: Access bypass

-------- DESCRIPTION ---------------------------------------------------------

This module enables you to upload multiple files at once in a webform. The module doesn't sufficiently check access to file deletion urls. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to edit all or their own webform submissions.

-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------

* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED ---------------------------------------------------

* webform_multifile 7.x-1.x versions prior to 7.x-1.5.

Drupal core is not affected. If you do not use the contributed Webform Multiple File Upload [4] module, there is nothing you need to do.

-------- SOLUTION ------------------------------------------------------------

Install the latest version:

* If you use the Webform Multiple File Upload module for Drupal 7.x, upgrade to Webform Multiple File Upload 7.x-1.6 [5]

Also see the Webform Multiple File Upload [6] project page.
