Project: File (Field) Paths [1] Date: 2018-August-15 Security risk: *Critical* 15∕25 AC:Basic/A:User/CI:Some/II:All/E:Theoretical/TD:Default [2] Vulnerability: Remote Code Execution

Description:  This module enables you to automatically sort and rename your uploaded files using token based replacement patterns to maintain a nice clean filesystem.

The module doesn't sufficiently sanitize the path while a new file is uploading, allowing a remote attacker to execute arbitrary PHP code.

This vulnerability is mitigated by the fact that an attacker must have access to a form containing a widget processed by this module.

Solution:  Install the latest version:

* If you use the filefield_paths module for Drupal 7.x, upgrade to filefield_paths 7.x-1.1 [3]
