CVE-2025-30139
📋 TL;DR
G-Net Dashcam BB GONX devices have hardcoded default Wi-Fi credentials that cannot be changed, allowing nearby attackers to connect to the dashcam's network. Once connected, attackers can intercept traffic from connected devices like smartphones. All users of these dashcams are affected as the vulnerability exists in default configuration.
💻 Affected Systems
- G-Net Dashcam BB GONX devices
📦 What is this software?
G Onx Firmware by Gnetsystem
⚠️ Risk & Real-World Impact
Worst Case
Attackers intercept sensitive data from connected smartphones (location data, app traffic, credentials), potentially leading to identity theft, stalking, or further network compromise.
Likely Case
Nearby attackers connect to dashcam network and monitor unencrypted traffic from connected devices, potentially capturing personal information and device identifiers.
If Mitigated
If dashcam is used in isolated environments without smartphone connections, risk is limited to unauthorized network access only.
🎯 Exploit Status
Attack requires physical proximity to dashcam Wi-Fi signal. No authentication needed to connect to network.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Contact vendor for firmware updates or replacement options.
🔧 Temporary Workarounds
Disable Wi-Fi functionality
allTurn off dashcam Wi-Fi broadcasting to prevent network access
Check device manual for Wi-Fi disable procedure
Physical isolation
allOnly use dashcam in secure locations where attackers cannot access Wi-Fi signal
🧯 If You Can't Patch
- Disconnect smartphone from dashcam Wi-Fi network when not actively transferring files
- Use dashcam in locations with limited public access to reduce attacker proximity
