CVE-2025-65553 — D3D Wi-Fi Home Security System ZX-G12 v2.1.17 is susceptible to RF jamming on the 433 MHz alarm sensor channel

Medium CVSS 6.5

D3D Wi-Fi Home Security System ZX-G12 v2.1.17 is susceptible to RF jamming on the 433 MHz alarm sensor channel. An attacker within RF range can transmit continuous interference to block sensor transmissions, resulting in missed alarms and loss of security monitoring. The device lacks jamming detection or mitigations, creating a denial-of-service condition that may lead to undetected intrusions or failure to trigger safety alerts.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
