CVE-2025-41418
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 · uneditedBuffer Overflow vulnerability exists in multiple versions of TB-eye network recorders and AHD recorders. The CGI process may be terminated abnormally by processing a specially crafted request.
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 · moderate confidenceBuffer overflow vulnerability in the CGI component of TB-eye network recorders and AHD recorders allows specially crafted HTTP requests to crash the CGI process, potentially leading to denial of service.

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 TB-eye recorder devices on your networkCheck your network device inventory or use network scanning to identify devices with manufacturer 'TB-eye' or product names including 'network recorder' or 'AHD recorder'. Look for devices exposing HTTP services on common ports 80/443.Affected if The device is a TB-eye network recorder or AHD recorder and exposes an HTTP management interface.
-
Confirm CGI component is accessibleAccess the device's HTTP interface and navigate to typical CGI paths such as /cgi-bin/ or check if CGI endpoints respond to requests. Use a web browser or curl to send a basic HTTP request to the device and examine the response headers.Affected if The device returns CGI-related responses or executes CGI scripts over HTTP.
-
Check if HTTP service is exposed to networkReview firewall rules, ACLs, or network segmentation configuration to determine if the recorder's HTTP port (typically 80/443) is accessible from untrusted networks. Use netstat or similar tools on the device if accessible, or perform external port scans.Affected if The HTTP management interface is reachable from networks outside the trusted management VLAN.
-
Identify firmware versionLog into the recorder's admin interface and look for system information, firmware version, or device info pages. Alternatively, check HTTP response headers or examine any accessible API endpoints that expose version metadata.Affected if The installed firmware version cannot be verified as patched or falls within an affected version range.
A system is affected if it is a TB-eye network recorder or AHD recorder with the CGI component exposed over HTTP, and the firmware version is unknown or within an affected range.

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-supplied firmware updates when available; until patched, restrict network access to recorder management interfaces and implement input validation at upstream network devices.
