CVE-2025-34042
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn authenticated command injection vulnerability exists in the Beward N100 IP Camera firmware version M2.1.6.04C014 via the ServerName and TimeZone parameters in the servetest CGI page. An attacker with access to the web interface can inject arbitrary system commands into these parameters, which are unsafely embedded into backend system calls without proper input sanitization. Successful exploitation results in remote code execution with root privileges. Exploitation evidence was observed by the Shadowserver Foundation on 2024-12-02 UTC.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAuthenticated command injection in Beward N100 IP Camera firmware M2.1.6.04C014 allows attackers with web interface access to inject arbitrary system commands via unsanitized ServerName and TimeZone parameters in the servetest CGI page, leading to root-level remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the camera's web interface or check the device label/menu to confirm it is a Beward N100 IP CameraAffected if The device is NOT a Beward N100 model (this CVE does not apply)
-
Check the firmware versionLog into the web interface and navigate to System > Firmware/Version, or use the CGI endpoint /cgi-bin/general?action=getDeviceInfo, to retrieve the installed firmware versionAffected if The installed firmware version is M2.1.6.04C014 or earlier (before vendor patch)
-
Confirm web interface accessibilityVerify that the camera's HTTP/HTTPS web interface is reachable from your network by attempting to access the login pageAffected if The web interface is exposed to untrusted networks (the vulnerability requires authenticated access)
-
Check for the servetest CGI endpointAttempt to access the URL /cgi-bin/servetest (or /cgi-bin/servetest.cgi) on the camera to see if the endpoint exists and respondsAffected if The servetest CGI page is present and responds (this is the vulnerable component)
You are affected if you have a Beward N100 IP Camera running firmware M2.1.6.04C014 or earlier, with the web interface accessible to untrusted users and the servetest CGI endpoint available.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware patch when available; until then, restrict web interface access to trusted networks only, disable the servetest CGI functionality if possible, and consider network segmentation or device replacement as compensating controls.
