CVE-2017-5174

This bug is like a lock that’s supposed to require a key, but for this camera it can be opened from the network without a login. Once someone gets in, they may be able to run code on the camera itself, which can let them spy, disrupt service, or use the camera as a foothold into your network.

This matters if you use Geutebruck IP Cameras, specifically the Geutebruck IP Camera G-Cam/EFD-2250 running Version 1.11.0.12. The findings indicate the vulnerability is network-reachable in the default configuration, and it does not require a login or any user action. The risk is highest when the camera can be reached from the network—especially if it’s exposed to the internet.

This is RED because attackers can bypass authentication over the network without any login or interaction, and public exploit code exists. The findings also indicate the device is reachable in default configuration, which increases the chance of real-world targeting. Act immediately to remove exposure and contain the device, because no fixed patch information is available right now.

1. Confirm exposure

   • Identify the exact camera model (Geutebruck IP Camera G-Cam/EFD-2250) and read the firmware version.
   • If the firmware is Version 1.11.0.12, treat the camera as vulnerable.

2. Confirm network reachability (from your side)

   • Check your router/firewall rules for port forwarding or open inbound access to the camera.
   • If you have remote access tooling, verify whether it can reach the camera from outside your local network.

3. Immediate mitigation if you cannot patch

   • Remove internet exposure: disable any port-forwarding for the camera and block inbound connections to it from the internet.
   • Restrict access by source IP where possible (allow only your admin workstation or VPN).
   • Isolate the camera: place it on a separate VLAN/guest network so that if the camera is compromised, it has limited ability to reach other business systems.

4. Find a real fix

   • Contact Geutebruck/vendor support and ask specifically for a firmware update that remediates CVE-2017-5174 for G-Cam/EFD-2250.
   • Available information here indicates no patch/firmware details are currently known; do not assume one exists until the vendor confirms.

5. Replacement planning (if no fix arrives quickly)

   • If the vendor cannot provide a fixed firmware in time, plan to replace the camera model/firmware with a supported, patched alternative.

6. What to monitor

   • After containment changes, watch for unusual inbound traffic to the camera’s IP and any unexpected outbound connections from it.
   • Review any device logs you can access for repeated failed or unusual requests (noting that this specific flaw can bypass authentication).

Severity is critical (CVSS 9.8) and the attack is network-based with no authentication and no user interaction required. The weakness is an authentication bypass (CWE-288) tied to the camera’s file system architecture, which can allow attackers to bypass access controls and potentially execute remote code. This has public exploit availability (1 known), and exploitation is therefore plausible. No KEV entry is listed, and no vendor patch information is available in the provided findings. EPSS is reported as predicted likelihood and trending upward, but the public exploit availability plus real risk posture drives remediation urgency. KEV means inclusion in CISA’s catalog of known exploited vulnerabilities; since it is not listed here, treat it as a high-risk flaw based on exploit availability and network reachability rather than on KEV confirmation.
