Lifecycle Timeline
2DescriptionCVE.org
D3D Wi-Fi Home Security System ZX-G12 v2.1.1 is vulnerable to RF replay attacks on the 433 MHz sensor communication channel. The system does not implement rolling codes, message authentication, or anti-replay protection, allowing an attacker within RF range to record valid alarm/control frames and replay them to trigger false alarms.
AnalysisAI
D3D Wi-Fi Home Security System ZX-G12 v2.1.1 is vulnerable to RF replay attacks on its 433 MHz sensor channel. No rolling codes, authentication, or anti-replay protection – attackers can record and replay alarm/control frames to trigger false alarms or disable sensors.
Technical ContextAI
The 433 MHz sensor communication lacks rolling codes, message authentication, and replay protection (CWE-294). An attacker with an SDR or simple 433 MHz receiver/transmitter can record valid frames and replay them at will.
RemediationAI
Replace with a security system using rolling codes (e.g., Z-Wave, Zigbee with encryption). No firmware fix can address fundamental RF protocol weaknesses.
