CVE-2025-50653
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 and mem parameters in the /time_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 · moderate confidenceA buffer overflow vulnerability exists in D-Link DI-8003 router firmware 16.07.26A1. The web interface endpoint /time_group.asp fails to properly validate the length of 'name' and 'mem' parameters before copying them into fixed-size buffers, allowing an attacker to overwrite adjacent memory by sending specially crafted HTTP requests.

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 management interface or check the device label to confirm the model is D-Link DI-8003Affected if Device is not a D-Link DI-8003 router - different models are not affected by this specific CVE
-
Check the firmware versionLog into the router's web interface and navigate to the System Status or Firmware Upgrade page to view the installed firmware version, or use SNMP/CLI if availableAffected if Firmware version is not 16.07.26A1 - only this exact version is listed as affected
-
Verify HTTP service availabilityCheck if the router's HTTP/HTTPS web management interface is running and accessible on the network by attempting to connect to the device's IP on ports 80 or 443Affected if The web interface is not running or not network-accessible - the vulnerability requires sending HTTP requests to the device
-
Confirm endpoint exposureCheck if the /time_group.asp endpoint is present by accessing http://[router-ip]/time_group.aspAffected if The /time_group.asp endpoint returns a valid HTTP response - this is the vulnerable page where the buffer overflow occurs via 'name' and 'mem' parameters
A D-Link DI-8003 router running firmware version 16.07.26A1 with its web management interface and /time_group.asp endpoint accessible on the network is affected by this buffer overflow vulnerability.

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 updates when available; if no update exists, disable or restrict access to the /time_group.asp web endpoint and implement network segmentation to limit exposure to untrusted users.
