Detailsinfo

A vulnerability was found in D3D Wi-Fi Home Security System ZX-G12 2.1.1. It has been classified as critical. Affected is an unknown part of the component Communication Channel Handler. The manipulation with an unknown input leads to a authentication replay vulnerability. CWE is classifying the issue as CWE-294. A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

This vulnerability is traded as CVE-2025-65552 since 11/18/2025. The exploitability is told to be difficult. The attack needs to be done within the local network. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1040.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
