Title

phpList < 3.7.0-RC5 Cross-Site Request Forgery via admins.php

Summary

phpList before 3.7.0-RC5 contains a cross-site request forgery (CSRF) vulnerability in lists/admin/admins.php. The administrator deletion action is triggered via an unauthenticated GET request (?page=admins&delete=N) that is not protected by a CSRF token (the central verifyCsrfGetToken check uses enforce=false and is bypassed when the token parameter is absent). A remote attacker can trick a logged-in super-administrator into loading a crafted URL (e.g., embedded as an image in an email) to delete any non-self administrator account.

Severity
