CVE-2023-50128

Alarm disarming via replayed radio command

Published Jan 11, 2024 · Updated Jul 9, 2026

Authentication bypass in Hozard alarm system 1.0 allows physically proximate attackers to disarm it via a replayed radio signal. The remote keyless transmitter emits the same radio-frequency command for each request, so a recorded disarm command remains valid when retransmitted. An attacker must be within radio range and capture a valid request; the demonstrated consequence is unauthorized disarming, not data access or service interruption.
