CVE-2025-6565
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 vulnerability was found in Netgear WNCE3001 1.0.0.50. It has been classified as critical. This affects the function http_d of the component HTTP POST Request Handler. The manipulation of the argument Host leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
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 stack-based buffer overflow vulnerability exists in the http_d function of the HTTP POST Request Handler in Netgear WNCE3001 firmware version 1.0.0.50. The vulnerability is triggered via manipulation of the Host HTTP header argument, allowing remote attackers to potentially execute arbitrary code. The exploit is publicly available and can be initiated 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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device administration interface or check the device label to confirm the model is Netgear WNCE3001Affected if The device is a Netgear WNCE3001 unit
-
Check the installed firmware versionLog into the device web interface and look for the firmware version in the administration settings, or use the device's web-based status page to retrieve the firmware version informationAffected if The firmware version is 1.0.0.50
-
Verify the HTTP service is running and accessibleAttempt to reach the device's HTTP interface by accessing its IP address on port 80 or 8080 from an authorized network locationAffected if The HTTP service is exposed and responding to requests
-
Review HTTP service logs for anomalous Host header activityIf the device supports logging or if network traffic logging is available, examine HTTP access logs for unusual or repeated requests with abnormally long Host header valuesAffected if Log evidence shows attempts to send oversized Host header values to the device
You are affected if you have a Netgear WNCE3001 device running firmware version 1.0.0.50 with its HTTP management interface accessible on the 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 any available firmware update from Netgear for the WNCE3001 device. If no update exists, consider network segmentation to limit exposure and monitor for indicators of compromise targeting the HTTP service.
