CVE-2021-33552: Geutebrück and UDP Technology cameras command injection

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 20 September 2026. Confidence: medium.

high priorityRemote code execution on internet-adjacent camera devices with a public exploit and very high EPSS, though exploitation requires valid admin credentials.

What it is

Multiple Geutebrück G-Cam and G-Code camera devices (and other UDP Technology-based cameras) are vulnerable to OS command injection, allowing remote arbitrary code execution. The flaw is in the camera firmware itself, so any exposed device is a potential foothold on the network.

Impact

An attacker who can reach the device and authenticate can execute arbitrary OS commands, gaining full control of the camera and a pivot point into the surveillance network.

Attack surface

Reachable over the network via the camera's web/management interface (CVSS vector AV:N). The vector requires high privileges (PR:H), so valid administrative credentials are needed; no user interaction is required.

Exploitation

Not listed in CISA KEV, but EPSS is high (0.488, ~98.8th percentile) and a public exploit reference exists, indicating meaningful real-world exploitation risk.

What to do

• Apply the vendor firmware updates referenced in CISA ICS advisory ICSA-21-208-03 as soon as they are available for each affected model.
• Isolate cameras on a dedicated VLAN with no route to corporate or internet-facing networks.
• Remove or restrict remote management access; block camera admin interfaces from untrusted networks.
• Change default and weak administrative credentials and enforce strong unique passwords.
• Monitor vendor advisories for these end-of-life-prone camera models and plan replacement if no fix is issued.

Detection

• Alert on unexpected outbound connections or command-shell activity originating from camera IP addresses.
• Monitor camera admin logins for anomalous source IPs, brute-force patterns, or logins outside maintenance windows.
• Inspect HTTP requests to camera management endpoints for shell metacharacters or command-injection payloads.
• Baseline normal camera traffic and flag deviations such as new listening ports or unusual processes.
