CVE Alert: CVE-2020-25079 – n/a – n/a

**Risk verdict**: High risk with active exploitation potential; treat as priority 1 due to KEV listing and confirmed network remote command injection.

**Why this matters**: An authenticated command injection on a network camera impacts confidentiality, integrity and availability, enabling remote code execution on the device. Attackers could disable or manipulate streams, exfiltrate footage, or pivot to adjacent systems, threatening both privacy and operational continuity in surveillance deployments.

**Most likely attack path**: Attacker must have valid credentials to access the device’s web interface (low privileges). From there, the network-facing CGI endpoint is leveraged to inject commands without user interaction, enabling full control of the device and potential lateral movement within a trusted segment if the camera is networked with other systems. The impact is high due to total compromise of affected devices.

**Who is most exposed**: IoT cameras deployed in office, retail, or campus networks with exposed management interfaces or insufficient network segmentation are most at risk; devices placed on or reachable from untrusted networks magnify exposure.

Detection ideas

• Unusual or elevated commands executed via the CGI endpoint (ddns_enc.cgi) in web logs.
• Anomalous authenticated sessions or spikes in camera management API activity.
• Rapid changes in device state or service restarts following CGI access.
• Access attempts from unexpected internal hosts or from outside the usual management network.

Mitigation and prioritisation

• Apply vendor hotfixes: upgrade to 1.06.01 Hotfix (DCS-2530L) or 2.02 (DCS-2670L) immediately.
• If patching is delayed, isolate devices from untrusted networks, and restrict management access to trusted hosts/networks.
• Strengthen authentication and rotate admin credentials; disable or tightly control external management interfaces.
• Monitor and alert on ddns_enc.cgi activity and related command execution patterns; implement network segmentation for surveillance gear.
• Treat as priority 1 given KEV presence and active exploitation indicators.
