CVE-2025-15045
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 · uneditedA flaw has been found in Tenda WH450 1.0.0.18. The affected element is an unknown function of the file /goform/Natlimit of the component HTTP Request Handler. This manipulation of the argument page causes stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been published and may be used.
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 confidenceA stack-based buffer overflow vulnerability exists in Tenda WH450 router firmware version 1.0.0.18 within the HTTP request handler for the /goform/Natlimit endpoint. The 'page' parameter is not properly bounds-checked before being copied to a stack-allocated buffer, allowing remote attackers to overflow the stack and potentially achieve 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 device modelAccess the router's web admin panel and look for the model information in System Status or Device Info. Alternatively, use network scanning tools like nmap or examine HTTP responses from the device to identify it as a Tenda WH450.Affected if Device is not a Tenda WH450 router - not affected
-
Check firmware versionIn the router's web admin panel, navigate to System Settings, Firmware Upgrade, or Status page to view the installed firmware version. Compare against 1.0.0.18.Affected if Firmware version is exactly 1.0.0.18 - likely affected
-
Test Natlimit endpoint accessibilitySend an HTTP GET or POST request to the /goform/Natlimit endpoint on the router (e.g., curl http://[router-ip]/goform/Natlimit). Check if the endpoint responds or requires authentication.Affected if The /goform/Natlimit endpoint is accessible without authentication or responds to requests
You are affected if you have a Tenda WH450 router running firmware version 1.0.0.18 where the /goform/Natlimit endpoint is accessible.

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 updates when available; until then, restrict administrative access to the device's web interface to trusted networks only or disable the Natlimit functionality if possible.
