* Advisory ID: DRUPAL-SA-CONTRIB-2016-018 * Project: HybridAuth Social Login [1] (third-party module) * Version: 7.x * Date: 2016-April-06 * Security risk: 9/25 ( Less Critical) AC:Complex/A:User/CI:Some/II:None/E:Theoretical/TD:Default [2] * Vulnerability: Information Disclosure, Open Redirect

-------- DESCRIPTION ---------------------------------------------------------

The HybridAuth Social Login module enables you to allow visitors to authenticate or login to a Drupal site using their identities from social networks like Facebook or Twitter.

.... Open redirect

The module doesn't verify the "destination" redirect after a login to be a non-external URL causing an open redirect vulnerability. This vulnerability can be used by any attacker crafting a special login link.

.... Information disclosure

The module doesn't check the tokens in the "destination" redirect value allowing an attacker to specify arbitrary tokens. Any token value is exposed in the redirect URL.

This vulnerability is mitigated by the fact that there must be secret data on the site that is exposed through the token system (for example an access protected field). An attacker must have a knowledge on what fields/tokens contain secret information.

-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
