Drupal Core 4.7.x Form Action Attribute Injection (4.7.0 - 4.7.3)

Description

Drupal Core is prone to a form action attribute injection vulnerability because it fails to properly verify user-supplied input. An attacker may leverage this issue to redirect Drupal form submissions to a third-party site under his control, thus gaining access to sensitive information such as e-mail addresses and possible other private profile data. Drupal Core versions 4.7.x ranging from 4.7.0 and up to and including 4.7.3 are vulnerable.

Remediation

Update to Drupal Core version 4.7.4 or latest
