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 · unedited
A vulnerability was detected in Tenda WH450 1.0.0.18. This affects an unknown part of the file /goform/L7Port of the component HTTP Request Handler. Performing a manipulation of the argument page results in stack-based buffer overflow. The attack may be initiated remotely. The exploit is now public 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 confidence

A stack-based buffer overflow vulnerability exists in Tenda WH450 router firmware version 1.0.0.18 within the HTTP Request Handler component for the /goform/L7Port endpoint. The 'page' parameter is not properly validated before being copied into a stack buffer, allowing remote unauthenticated attackers to potentially execute arbitrary code by sending specially crafted HTTP requests.

MitigationImmediately restrict network access to the device's web management interface (disable remote WAN access if enabled), network-segment the device, and monitor for signs of exploitation until a vendor firmware patch is available; if the device is end-of-life, consider replacement.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the router model
    Check the device label or access the router's web interface and look for the model number in the system status or device info page
    Affected if The device is not a Tenda WH450 router (the vulnerability only affects this specific model)
  2. Check the firmware version
    Access the router's web interface, navigate to System Settings or Firmware Upgrade section, and verify the firmware version displayed. Alternatively, check the firmware file name or version string if you have local access to the firmware image
    Affected if The firmware version is 1.0.0.18 (this is the only affected version listed)
  3. Verify L7Port functionality is accessible
    Attempt to access the /goform/L7Port endpoint via HTTP request (e.g., curl http://<router-ip>/goform/L7Port?page=test) or check if the L7Port feature is enabled in the router's web interface under port forwarding or firewall settings
    Affected if The /goform/L7Port endpoint responds or the L7Port feature is enabled - the buffer overflow occurs when the 'page' parameter is manipulated
  4. Confirm remote web interface access
    Check if the router's HTTP web interface is accessible from outside the local network by testing remote IP access or reviewing firewall/NAT port forwarding rules for port 80/443
    Affected if Remote access to the router's web interface is enabled - the CVSS vector indicates this can be exploited remotely, making the router reachable from the internet a key factor

You are affected if you own a Tenda WH450 router running firmware version 1.0.0.18 with the L7Port feature or web interface accessible, particularly from remote networks.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Immediately restrict network access to the device's web management interface (disable remote WAN access if enabled), network-segment the device, and monitor for signs of exploitation until a vendor firmware patch is available; if the device is end-of-life, consider replacement.
