Drupal FileField Source Module < 6.x-1.2 Arbitrary Code Execution

Medium

Synopsis

The remote web server is hosting a web application that is vulnerable to a remote code execution attack.

Description

The remote web server hosts a Drupal install that uses the FileField Source module.

Versions of FileField Sources earlier than 6.x-1.2 are potentially affected by a remote code execution vulnerability because the application fails to properly sanitize the file extensions of files that have been transferred from remote servers.

Solution

Upgrade to Drupal FileField Sources module 6.x-1.2 or later.
