⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers can reconfigure FM transmission settings, potentially broadcasting unauthorized content, and gain persistent access to the administrative interface.
Likely Case
Attackers gain administrative access to modify FM station settings, potentially disrupting broadcasts or injecting unauthorized content.
If Mitigated
If network segmentation and access controls are properly implemented, impact is limited to unauthorized administrative access within the isolated network segment.
🎯 Exploit Status
Exploitation requires only a simple HTTP request to the vulnerable endpoint with no authentication or special tools needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to the FM transmitter's web interface to trusted IP addresses only
iptables -A INPUT -p tcp --dport [WEB_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [WEB_PORT] -j DROP
Web Server Configuration
allAdd authentication requirements to the system.cgi endpoint or disable it entirely
# Edit web server configuration to add authentication to /system.cgi
# Or rename/remove the system.cgi file
🧯 If You Can't Patch
- Isolate the FM transmitter on a separate VLAN with strict network access controls
- Implement a reverse proxy with authentication in front of the web interface
🔍 How to Verify
Check if Vulnerable:
Send HTTP GET request to http://[device_ip]/system.cgi and check if admin password is returned in responseCheck Version:
Check web interface footer or about page for version informationVerify Fix Applied:
Attempt the same HTTP request and verify no sensitive information is returned📡 Detection & Monitoring
Log Indicators:
- HTTP GET requests to /system.cgi from unauthorized IP addresses
- Multiple failed login attempts followed by successful login
Network Indicators:
- HTTP traffic to /system.cgi endpoint from external IPs
- Unusual administrative access patterns
