• Advisory ID: DRUPAL-SA-CONTRIB-2015-127
• Project: HybridAuth Social Login (third-party module)
• Version: 7.x
• Date: 2015-June-24
• Security risk: 8/25 ( Less Critical) AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:Uncommon
• Vulnerability: Access bypass

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.

The module allows account creation through social login when the configuration is set to allow user registration by administrators only.

This vulnerability is mitigated by the fact that a site must be configured to allow user registration by administrators only and that authenticated user accounts can access sensitive data that would otherwise not be shown to anonymous users.

CVE identifier(s) issued

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

Versions affected

• HybridAuth Social Login 7.x-2.x versions prior to 7.x-2.13.
