Drupal Core - Overlay - Less Critical - Open Redirect - SA-CORE-2015-004

October 21, 2015 - 12:16pm
Description

The Overlay module in Drupal core displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.

This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.

An incomplete fix for this issue was released as part of SA-CORE-2015-002.

  • A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.
