Summary
Geutebrück E2 series IP cameras contain an OS command injection vulnerability that allows a remote attacker with administrative credentials to inject and execute arbitrary OS commands with root privileges. The vulnerability affects firmware versions prior to 1.12.0.25. Successful exploitation could allow an attacker to modify camera settings, disable surveillance, access recorded footage, or pivot into the facility network.
What this means
What could happen
An attacker with administrative access to a Geutebrück E2 camera could run arbitrary commands as root, potentially altering camera configuration, disabling surveillance, or using the device as a pivot point into your network.
Who's at risk
Any organization using Geutebrück E2 series IP cameras for surveillance in industrial facilities, water/electric utilities, or critical infrastructure. This includes security monitoring in control rooms, perimeter surveillance, and facility monitoring systems.
How it could be exploited
An attacker must authenticate to the camera's web interface using valid administrative credentials, then inject OS commands through an input field (likely in configuration or settings). The commands execute with root privileges on the camera.
Prerequisites
- Valid administrative (root-level) credentials for the camera
- Network access to the camera's web management interface (typically port 80/443)
- Camera running firmware version 1.12.0.25 or earlier
Remotely exploitable via web interfaceRequires valid credentials (mitigating factor)Command injection leads to root accessLow public awareness (CISA advisory from 2018)Affects physical security infrastructure
Exploitability
Moderate exploit probability (EPSS 1.5%)
