CVE-2025-50671
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 parameters in the /xwgl_ref.asp endpoint. An attacker can exploit this vulnerability by sending a crafted HTTP GET request with excessively long strings in parameters name, en, user_id, shibie_name, time, act, log, and rpri.
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 confidenceBuffer overflow vulnerability in D-Link DI-8003 router firmware 16.07.26A1 allows remote attackers to crash the device or potentially execute arbitrary code via excessively long strings in multiple parameters (name, en, user_id, shibie_name, time, act, log, rpri) sent to the /xwgl_ref.asp web endpoint.

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 admin interface and navigate to Status or System Info page to verify the device model number displays as DI-8003 or DI-8003 SeriesAffected if Device model is not D-Link DI-8003 - the vulnerability does not apply
-
Check installed firmware versionIn the router web interface, go to Status or System Settings page and locate the firmware version field; compare it to 16.07.26A1Affected if Firmware version equals exactly 16.07.26A1 - this is the affected version
-
Verify web management interface is enabledIn router settings, check under Administration or System Management for HTTP/HTTPS access settings; confirm the web interface is turned on and accessibleAffected if Web interface is enabled and accessible - the attack surface exists
-
Test for vulnerable endpoint accessibilityIn router admin, view System Log or Security Log sections; look for timestamps matching when the web interface was accessed, entries mentioning process crashes, or unexpected device rebootsAffected if Logs show unexplained crashes, process failures, or restarts occurring after web interface access
A user is affected if they have a D-Link DI-8003 router running firmware version 16.07.26A1 with the web management interface enabled and the /xwgl_ref.asp endpoint accessible on their 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 access to the router's management interface via firewall rules or disable remote management to prevent unauthenticated exploitation.
