CVE-2020-28713

Incorrect access control in push notification service in Night Owl Smart
Doorbell FW version 20190505 allows remote users to send push notification
events via an exposed PNS server. A remote attacker can passively record
push notification events which are sent over an insecure web request. The
web service does not authenticate requests, and allows attackers to send an
indefinite amount of motion or doorbell events to a user’s mobile
application by either replaying or deliberately crafting false events.
