The module does not sufficiently enforce these access restrictions across all supported authentication mechanisms. As a result, a blocked administrative user may still be able to authenticate through certain alternative authentication methods. This vulnerability is mitigated by the fact that an attacker must possess valid credentials for a user with the administrator role, and must authenticate using a less commonly used authentication mechanism. Solution: Install the latest version: * If you use the Stop Administrator Login module, upgrade to Stop Administrator Login 8.x-1.6 [3] Reported By: * Pierre Rudloff (prudloff) [4] of the Drupal Security Team Fixed By: * Bram Driesen (bramdriesen) [5] of the Drupal Security Team Coordinated By: * Swan Kalata (akalata) [6] of the Drupal Security Team * Bram Driesen (bramdriesen) [7] of the Drupal Security Team * Greg Knaddison (greggles) [8] of the Drupal Security Team * Juraj Nemec (poker10) [9] of the Drupal Security Team * Pierre Rudloff (prudloff) [10] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [11] [1] https://www.drupal.org/project/stop_admin [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/stop_admin/releases/8.x-1.6 [4] https://www.drupal.org/u/prudloff [5] https://www.drupal.org/u/bramdriesen [6] https://www.drupal.org/u/akalata [7] https://www.drupal.org/u/bramdriesen [8] https://www.drupal.org/u/greggles [9] https://www.drupal.org/u/poker10 [10] https://www.drupal.org/u/prudloff [11] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal....
