CVE-2025-14879
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 weakness has been identified in Tenda WH450 1.0.0.18. Affected is an unknown function of the file /goform/onSSIDChange of the component HTTP Request Handler. This manipulation of the argument ssid_index causes stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks.
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 confidenceStack-based buffer overflow in Tenda WH450 router firmware version 1.0.0.18. The vulnerability exists in the HTTP request handler for the /goform/onSSIDChange endpoint where the ssid_index parameter is not properly validated before being used in a stack-allocated buffer. This allows remote attackers to overwrite stack memory and potentially execute arbitrary code.

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 modelCheck the router label or access the admin web interface to confirm the model is Tenda WH450Affected if The device is not a Tenda WH450 router
-
Check the firmware versionLog into the router admin panel (typically at 192.168.0.1) and navigate to System Settings > Firmware Update, or use the command 'cat /proc/version' via telnet/SSH if available, to determine the installed firmware versionAffected if The firmware version is 1.0.0.18
-
Verify the web management interface is accessibleAttempt to access the router's HTTP interface at the default gateway IP (commonly 192.168.0.1) from a browserAffected if The web interface is accessible and responds to HTTP requests
-
Confirm the vulnerable endpoint existsSend an HTTP GET or POST request to http://[router-ip]/goform/onSSIDChange using curl or a similar tool to verify the endpoint respondsAffected if The /goform/onSSIDChange endpoint responds (indicates the HTTP handler is active)
-
Check if remote management is enabledIn the router admin panel, look for 'Remote Management' or 'Remote Access' settings under Advanced or Security settings to see if external HTTP access is permittedAffected if Remote management is enabled, allowing unauthenticated or low-auth access to the vulnerable endpoint from the WAN
A user is affected if they have a Tenda WH450 router running firmware version 1.0.0.18 with the web interface accessible, particularly if remote management is enabled.

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 update when available. If no update exists, immediately isolate the device on a restricted network segment or replace with a supported device. Disable remote management interfaces if not required.
