CVE-2025-53702
📋 TL;DR
Vilar VS-IPC1002 IP cameras are vulnerable to denial-of-service attacks via unauthenticated network requests. An attacker on the same local network can send a crafted request to the /cgi-bin/action endpoint, causing the device to become completely unresponsive and requiring manual restart. Only version 1.1.0.18 was confirmed vulnerable, but other versions may also be affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Persistent DoS attacks could render critical surveillance cameras permanently unavailable until manually restarted, creating security blind spots.
Likely Case
Local network attackers temporarily disable cameras, disrupting monitoring capabilities until physical intervention.
If Mitigated
With proper network segmentation, impact is limited to isolated camera networks with minimal operational disruption.
🎯 Exploit Status
Exploitation requires only network access and knowledge of the vulnerable endpoint; no authentication or special tools needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - vendor unresponsive
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider network segmentation and access controls as primary mitigation.
🔧 Temporary Workarounds
Network Segmentation
allIsolate cameras on dedicated VLANs with strict access controls to prevent unauthorized network access.
Firewall Rules
allBlock access to /cgi-bin/action endpoint from untrusted networks using firewall or web application firewall rules.
🧯 If You Can't Patch
- Segment cameras onto isolated networks with no internet access
- Implement strict network access controls allowing only authorized management systems to communicate with cameras
🔍 How to Verify
Check if Vulnerable:
Check if camera responds to crafted requests to http://[camera-ip]/cgi-bin/action endpoint from local networkCheck Version:
Check camera web interface or documentation for firmware version; version 1.1.0.18 is confirmed vulnerableVerify Fix Applied:
Test if camera remains responsive after sending crafted requests to the vulnerable endpoint📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /cgi-bin/action endpoint from single source
- Camera service crashes or restarts
Network Indicators:
- Unusual traffic patterns to camera CGI endpoints
- Sudden loss of camera network connectivity
