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]
