CVE-2026-2260
📋 TL;DR
This CVE describes a remote command injection vulnerability in D-Link DCS-931L IP cameras. Attackers can execute arbitrary operating system commands by manipulating the AdminID parameter in the /goform/setSysAdmin endpoint. This affects all DCS-931L cameras running firmware version 1.13.0 or earlier, which are no longer supported by the vendor.
💻 Affected Systems
- D-Link DCS-931L
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full device compromise allowing attackers to install persistent malware, pivot to internal networks, disable the camera, or use the device for botnet activities.
Likely Case
Unauthorized access to camera feeds, device configuration changes, or using the device as a foothold for further network attacks.
If Mitigated
Limited impact if device is isolated in a restricted network segment with proper firewall rules and monitoring.
🎯 Exploit Status
Public proof-of-concept exploit code is available on GitHub, making exploitation trivial for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None available
Vendor Advisory: None - product is end-of-life
Restart Required: No
Instructions:
No official patch exists. The vendor has discontinued support for this product. Immediate replacement is recommended.
🔧 Temporary Workarounds
Network Segmentation
allIsolate DCS-931L cameras in a separate VLAN with strict firewall rules blocking all inbound traffic except necessary management ports from trusted sources.
Web Interface Disable
allDisable the web administration interface if not required, or restrict access to specific management IP addresses only.
🧯 If You Can't Patch
- Immediately remove affected devices from internet-facing deployments
- Implement strict network access controls allowing only outbound traffic to required services
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface at http://[camera-ip]/system.html or via SSH if enabled. Version 1.13.0 or earlier indicates vulnerability.Check Version:
curl -s http://[camera-ip]/system.html | grep -i firmwareVerify Fix Applied:
No fix available to verify. Only complete device replacement with a supported model can resolve this vulnerability.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/setSysAdmin with shell metacharacters in parameters
- Failed authentication attempts followed by successful command execution
Network Indicators:
- Unusual outbound connections from camera to external IPs
- Traffic patterns indicating command-and-control communication
