The Hosting HTTPS module is a commonly used piece of the Aegir platform. This module doesn't sufficiently shield multi-site installations. This vulnerability is mitigated by the fact that the server must be using Apache and must host multiple sites on a common platform. An attacker must have a knowledge about used filenames and the server. Solution:  Install the latest version: * If you use Aegir hosting system, upgrade to Aegir HTTPS 7.x-3.170 [3] Also see the Aegir HTTPS [4] project page.
