CVE-2021-3789

Firmware decryption-key disclosure through physical access

Published Nov 12, 2021 · Updated Aug 3, 2024

Information disclosure in Motorola Binatone Hubble Cameras allows physically proximate attackers to obtain firmware-package decryption keys. The vendor identifies the affected locus only as the device and does not disclose how the key is stored or recovered from it. Physical possession of an affected camera is required, and the exposed key permits firmware-package decryption without reported data modification or service interruption.
