The D-Link DIR-816 A2 1.11 router only checks the random token when authorizing a goform request. An attacker can get this token from dir_login.asp and use an API URL /goform/form2userconfig.cgi to edit the system account without authentication.
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
