CVE-2024-31800
📋 TL;DR
This vulnerability allows attackers with physical access to GNCC's GC2 Indoor Security Camera 1080P to bypass authentication and gain privileged command shell access via the UART debugging port. This affects users of this specific camera model who have not disabled or secured the debugging interface. Physical access to the device is required for exploitation.
💻 Affected Systems
- GNCC GC2 Indoor Security Camera 1080P
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker gains full administrative control of the camera, can disable security features, access video feeds, modify firmware, or use the device as a network pivot point.
Likely Case
Attacker with brief physical access extracts credentials, disables camera functionality, or installs persistent backdoor.
If Mitigated
With proper physical security controls, the vulnerability cannot be exploited as physical access is prevented.
🎯 Exploit Status
Exploitation requires physical access and basic hardware tools to connect to UART pins. No authentication needed once physical connection is established.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Contact vendor GNCC for firmware updates or hardware revision information.
🔧 Temporary Workarounds
Disable UART Debug Port
allPhysically disable or obscure the UART debugging port on the device
Apply Epoxy to UART Pins
allUse non-conductive epoxy to cover UART contact points to prevent physical connection
🧯 If You Can't Patch
- Implement strict physical security controls to prevent unauthorized access to devices
- Deploy cameras in tamper-evident enclosures or secure locations
🔍 How to Verify
Check if Vulnerable:
Physically inspect device for exposed UART pins or test with UART-to-USB adapter to check for accessible shell
Check Version:
No version-specific command; vulnerability exists in all versions with exposed UART
Verify Fix Applied:
Verify UART port is physically inaccessible or test connection attempt fails
