How the CVE Works
CVE-2025-30142 exploits weak MAC address verification in G-Net Dashcam BB GONX devices. The dashcam relies solely on MAC addresses to authenticate paired devices. Attackers can perform ARP scanning to capture a trusted device’s MAC address, then spoof it to bypass pairing. This grants unauthorized access, enabling control over the dashcam’s functions, including video feeds and settings. No cryptographic checks or additional authentication layers are enforced, making spoofing trivial.
DailyCVE Form
