CVE-2025-50655
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 /thd_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 firmware 16.07.26A1 allows remote attackers to overflow a buffer via the name parameter in the /thd_group.asp web endpoint, potentially leading to remote 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.
-
Identify the device modelAccess the router's web administration interface and check the device info page, or check the device label/markings on the hardware unit.Affected if The device is not a D-Link DI-8003 router.
-
Check the installed firmware versionLog into the router web interface and navigate to System > Firmware Upgrade or Status page to view the firmware version. Alternatively, check via CLI if available.Affected if The firmware version is not exactly 16.07.26a1.
-
Verify the web server is reachableAttempt to access the router's web interface by entering the router's IP address in a web browser. Look for the login page or any response from the /thd_group.asp endpoint.Affected if The web interface is not accessible from your location.
-
Confirm remote management is enabledIn the router web interface, navigate to Management > Remote Management or Access Control settings to check if remote web access is enabled. Check if the management interface is bound to WAN IP or any external IP.Affected if Remote management is enabled and the web interface is accessible from untrusted networks.
You are affected if you have a D-Link DI-8003 router running firmware version 16.07.26a1 with its web management interface accessible remotely, since the buffer overflow vulnerability in the /thd_group.asp endpoint can be exploited via the name parameter.

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 dataIf vendor firmware is available, update immediately; otherwise, restrict access to the device's management interface using network segmentation or firewall rules to limit exposure to trusted sources only.
