CVE-2021-3790

Camera service interruption via local web server overflow

Published Nov 12, 2021 · Updated Aug 3, 2024

A stack-based buffer overflow in Motorola Binatone Hubble Camera local web servers allows remote attackers to interrupt camera service. The vendor identifies the local web server as the affected component but has not disclosed the request handler or operation that overruns the stack buffer. No account or user interaction is required, but the attacker must share the camera's network; the documented consequence is camera-service interruption only.
