CVE-2025-50652
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 · uneditedAn issue in D-Link DI-8003 16.07.26A1 related to improper handling of the id parameter in the /saveparm_usb.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 confidenceThe D-Link DI-8003 router firmware 16.07.26A1 contains a vulnerability in the /saveparm_usb.asp web endpoint where the id parameter is not properly validated or sanitized. This improper handling could allow an attacker to inject malicious input through the id parameter, potentially leading to command injection, SQL injection, or other parameter-based attacks depending on how the parameter is processed server-side.

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 D-Link DI-8003 router modelAccess the router admin panel or check the device label to confirm the model is DI-8003Affected if The device is not a D-Link DI-8003 router, then this CVE does not apply
-
Check the installed firmware versionLog into the router web interface and navigate to the status or system information page to find the firmware version, or use the command 'telnet/router_ip' and check the firmware version via the admin panelAffected if The firmware version is not exactly 16.07.26a1, then this CVE does not apply (only this specific version is affected)
-
Verify the web management interface is enabledAttempt to access the router login page at http://router_ip/ and confirm the page loads successfullyAffected if The web interface is disabled or inaccessible, the vulnerable endpoint is not reachable
-
Confirm the vulnerable endpoint existsSend an HTTP GET or POST request to http://router_ip/saveparm_usb.asp and check if the endpoint respondsAffected if The endpoint returns a 404 or does not exist, the vulnerability cannot be exploited
The device is affected only if it is a D-Link DI-8003 router running firmware version 16.07.26a1 AND the web management interface is enabled AND the /saveparm_usb.asp 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 dataRestrict network access to the router's web management interface, preferably through a VLAN or by disabling remote management. If available, apply any vendor firmware updates. Consider disabling USB features if not needed.
