CVE-2025-50662
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 buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper handling of the name parameter in the /url_group.asp endpoint.
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 confidenceA buffer overflow vulnerability in D-Link DI-8003 router firmware 16.07.26A1 allows remote attackers to overflow a buffer via the name parameter in the /url_group.asp endpoint, potentially leading to code execution or 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.
-
Confirm device model is D-Link DI-8003Access the router's web interface or check the device label/management console to verify the model number is DI-8003Affected if The device is not a D-Link DI-8003 router (different models are not affected by this specific CVE)
-
Identify installed firmware versionLog into the router's web management interface and navigate to the System or Status section to view the firmware version; alternatively, check via CLI if available or examine the firmware file if you have access to itAffected if The firmware version is exactly 16.07.26A1 (this is the only affected version)
-
Verify /url_group.asp endpoint is reachableAttempt to access http://[router-ip]/url_group.asp from a client on the network to confirm the web interface is active and this endpoint respondsAffected if The endpoint returns an HTTP response (the buffer overflow requires this endpoint to be accessible)
-
Check if remote management is enabledIn the router's web interface, examine the Administration or Management settings to determine if remote web access from external networks is permittedAffected if Remote management/access to the web interface is enabled from untrusted networks (this increases exposure to the remote attack vector)
You are affected if you are running D-Link DI-8003 firmware version 16.07.26A1 and the /url_group.asp endpoint is accessible on your network.

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 if available; otherwise, restrict or disable remote access to the device management interface, or replace the end-of-life device with a currently supported model.
