SinoTrack GPS Receiver Weak Authentication

A username and password are required to authenticate to the central SinoTrack device management interface. The username for all devices is an identifier printed on the receiver. The default password is well-known and common to all devices. Modification of the default password is not enforced during device setup. A malicious actor can retrieve device identifiers with either physical access or by capturing identifiers from pictures of the devices posted on publicly accessible websites such as eBay.
