📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker gains full administrative control over the CCTV system, potentially disabling cameras, accessing sensitive footage, or using the system as a foothold for further network attacks.
Likely Case
Unauthorized users escalate privileges to administrator level, gaining control over camera feeds, system settings, and potentially other connected security systems.
If Mitigated
With proper access controls and network segmentation, impact is limited to the CCTV system itself without lateral movement to other systems.
🎯 Exploit Status
Exploitation requires low-privileged access first. The CWE-284 classification indicates improper access control, suggesting manipulation of authorization mechanisms.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/inadequate-access-control-demes-group-products
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. Apply any available patches. 3. Verify authorization controls are properly implemented.
🔧 Temporary Workarounds
Network Segmentation
allIsolate the CCTV system from other network segments to limit potential lateral movement.
Access Control Review
allAudit and strengthen user permission assignments, ensuring least privilege principles.
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the CCTV web interface
- Monitor for unusual privilege escalation attempts and review access logs regularly
🔍 How to Verify
Check if Vulnerable:
Check the web service version via the interface or configuration files. If version is 2.616.BY00.11, the system is vulnerable.Check Version:
Check web interface or configuration files for version information (specific command depends on implementation)Verify Fix Applied:
Test authorization controls by attempting to access administrator functions with low-privileged accounts after applying mitigations.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authorization attempts followed by successful admin access from low-privileged accounts
- Unusual user privilege changes in system logs
Network Indicators:
- HTTP requests to camera control endpoints from unauthorized IPs or users
- Unusual traffic patterns to administrative interfaces
