Acquia Cloud Site Factory provides an environment and a robust set of tools that simplify management of many Drupal sites, allowing you to quickly deliver and manage any number of websites.

The module ships with a modified version of the core Overlay JavaScript file, which is vulnerable to an open redirect attack (see SA-CORE-2015-002).

Only sites with the Overlay module enabled are vulnerable.
