CVE-2025-30142
Bypassing of Device Pairing can occur.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered on G-Net Dashcam BB GONX devices. Bypassing of Device Pairing can occur. It uses MAC address verification as the sole mechanism for recognizing paired devices, allowing attackers to bypass authentication. By capturing the MAC address of an already-paired device through ARP scanning or other means, an attacker can spoof the MAC address and connect to the dashcam without going through the pairing process. This enables full access to the device.
