CVE-2023-50126

Alarm disarmament via unencrypted RFID tag cloning

Published Jan 11, 2024 · Updated Jun 3, 2025

Missing encryption in Hozard Alarmsysteem 1.0 RFID tags allows physically proximate attackers to clone a tag and disarm the alarm. The RFID credential stores or transmits clonable identification data without cryptographic protection, allowing it to be copied during brief proximity. Access near an enrolled tag is required; the clone impersonates that tag to change the alarm from armed to disarmed without authorization.
