CVE-2021-3792

Vulnerability

Some device communications in Motorola-branded Binatone Hubble Cameras (various models) that use backend Hubble services are transmitted without encryption. This vulnerability affects firmware versions prior to the patch released in the vendor advisory [1].

Exploitation

An attacker with network access to the device's traffic can intercept unencrypted communications between the camera and Hubble backend services. No authentication or user interaction is required; the attacker only needs to be on the same network or have the ability to monitor the communication path.

Impact

By accessing the unencrypted communication channel, an attacker can obtain sensitive information transmitted between the device and backend, such as credentials, configuration data, or video stream metadata. This leads to information disclosure and potential privilege escalation.

Mitigation

The vendor has released a security advisory [1] that includes firmware updates addressing this vulnerability. Users should update their device firmware to the latest version available. If no update is available, network segmentation and encryption (e.g., VPN) can reduce exposure.
