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 buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to inadequate validation of input size in the routes_static parameter in the /router.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 · moderate confidence

A buffer overflow vulnerability exists in D-Link DI-8003 router firmware 16.07.26A1. The routes_static parameter in the /router.asp endpoint does not validate input size properly, allowing an attacker to overflow a buffer via crafted HTTP requests.

MitigationIf available, apply vendor firmware updates; otherwise, restrict network access to the router's management interface to trusted sources only, as this vulnerability is exploitable remotely without authentication.

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 device model
    Access the device web interface or check the device label/marketing to confirm it is a D-Link DI-8003 router.
    Affected if The device is not a D-Link DI-8003 model.
  2. Check the firmware version
    Log into the router web interface and navigate to the Status or System Info page to view the firmware version, or use the command interface to query the firmware version (for example, via telnet or SSH if enabled).
    Affected if The firmware version is exactly 16.07.26a1.
  3. Verify the vulnerable endpoint exists
    Attempt to access the /router.asp endpoint on the device by navigating to it via the web browser (for example, http://<device_ip>/router.asp).
    Affected if The /router.asp page is accessible and loads successfully.
  4. Confirm routes_static parameter is present
    Inspect the HTML source of the /router.asp page or submit a GET/POST request to the endpoint and look for a form parameter named 'routes_static' or similar static route configuration fields.
    Affected if The routes_static parameter is found in the router.asp page.

A user is affected only if the device is a D-Link DI-8003 running firmware version 16.07.26a1 with the /router.asp web interface accessible and the routes_static parameter present.
