By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2013-084
  • Project: FileField Sources (third-party module)
  • Version: 6.x, 7.x
  • Date: 2013-October-30
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Access bypass

Description

This module expands on the FileField module by allowing you to select new or existing files through additional means, such as re-using files with an auto-complete textfield, attaching server-side files uploaded via FTP, transferring file files from a remote server, pasting a file directly from the clipboard, and selecting existing files through the IMCE file browser.

The module doesn't sufficiently check file access permissions when attaching an existing file. Any existing file could be re-used and the user would then be granted access to that file.

This vulnerability is mitigated by the fact that an attacker must have a permission granting the ability to create content which has a file field using the module.
