DescriptionInsecure access control in ZKTeco BioTime through 9.0.1 allows authenticated attackers to escalate their privileges due to the fact that session ids are not validated for the type of user accessing the application by default. Privilege restrictions between non-admin and admin users are not enforced and any authenticated user can leverage admin functions without restriction by making direct requests to administrative endpoints.
