Open Social - Critical - Insecure Session Management - SA-CONTRIB-2019-075

Project: Open Social
Date: 2019-November-06
Security risk: Critical 15∕25
Vulnerability: Insecure Session Management

Description

Open Social is a Drupal distribution for online communities. The included social_magic_login module doesn't sufficiently validate magic login URLs for user accounts that do not have a local password, but login via external systems. The lack of validation makes it possible for an adversary to forge valid login URLs and login to such an account.

This vulnerability is mitigated by the fact the module social_magic_login needs to be enabled.

Solution

Install the latest version:

If you use the Open Social distribution for Drupal 8.x-7.x, upgrade to open social 8.x-7.1
If you use the Open Social distribution for Drupal 8.x-6.x, upgrade to open social 8.x-6.5
Alternatively, disable the module social_magic_login.
