CVE-2025-30142

Full device access via paired MAC spoofing

Published Mar 18, 2025 · Updated Mar 25, 2025

Authentication bypass in G-Net Dashcam BB GONX devices allows remote attackers to gain full device access by spoofing a paired MAC address. The pairing mechanism treats the connecting client's MAC address as the sole proof of prior pairing instead of verifying an unforgeable credential. An attacker must reach the dashcam's local network and learn an already paired address, after which the spoofed client receives the device access granted to that identity.
