CVE-2023-31191
📋 TL;DR
This vulnerability allows attackers to inject spoofed drone identification messages that force the DroneScout ds230 receiver to drop real drone location data and transmit fake information instead. This affects organizations using DroneScout ds230 Remote ID receivers for drone tracking and monitoring, potentially compromising airspace security.
💻 Affected Systems
- BlueMark Innovations DroneScout ds230 Remote ID receiver
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete loss of legitimate drone tracking data, enabling unauthorized drone operations, airspace violations, or drone-based attacks while appearing legitimate to monitoring systems.
Likely Case
Intermittent loss of drone tracking data, creating blind spots in drone monitoring systems and allowing unauthorized drone activity to go undetected.
If Mitigated
Limited impact with proper network segmentation and monitoring, though some data loss may still occur during attack windows.
🎯 Exploit Status
Requires specialized RF equipment and knowledge of drone communication protocols, but no authentication or network access needed.

🔍 How to Verify
Check if Vulnerable:
Check firmware version via device web interface or SSH connection. Vulnerable if version is between 20211210-1627 and 20230329-1042 inclusive.Check Version:
ssh admin@dronescout-ip 'cat /etc/version' or check web interface at http://dronescout-ip/statusVerify Fix Applied:
Confirm firmware version is newer than 20230329-1042 and test with legitimate drone signals to ensure proper reception.📡 Detection & Monitoring
Log Indicators:
- Sudden loss of legitimate drone MQTT messages
- Unusual patterns in drone ID data
- Multiple drones reporting identical or impossible locations
Network Indicators:
- Abnormal MQTT message patterns
- Suspicious RF signal strength variations near receivers
