CVE-2024-51000
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 · uneditedNetgear R8500 v1.0.2.160 was discovered to contain multiple stack overflow vulnerabilities in the component wireless.cgi via the opmode, opmode_an, and opmode_an_2 parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted POST request.
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 confidenceStack overflow vulnerability in the wireless.cgi component of Netgear R8500 v1.0.2.160 allows attackers to cause DoS via crafted POST requests to the opmode, opmode_an, and opmode_an_2 parameters. The vulnerability occurs because these parameters do not properly validate input length before copying to stack buffers.

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 router modelCheck the device label or web interface for the exact model number (R8500)Affected if Model is not Netgear R8500
-
Check the firmware versionAccess the router's web management interface, navigate to Administration > Firmware Update or Advanced > Administration > Router Update, and note the current firmware versionAffected if Firmware version is exactly 1.0.2.160
-
Verify wireless.cgi accessibilityAttempt to access the wireless.cgi endpoint on the router (typically at http://<routerIP>/wireless.cgi)Affected if The wireless.cgi script is accessible and responds to requests
-
Confirm POST parameter exposureCheck if the router's web interface has wireless configuration pages that submit to the opmode, opmode_an, or opmode_an_2 parameters via POSTAffected if These parameters are available in the web interface and accept user input
-
Check remote administration statusIn the router web interface, go to Advanced > Administration > Remote Management and verify if remote management is enabledAffected if Remote administration is enabled, allowing external attackers to reach the vulnerable component
The device is affected if it is a Netgear R8500 running firmware version 1.0.2.160 and the wireless.cgi interface is accessible (locally or remotely via remote administration).

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 update when available; until then, restrict access to the router's web management interface to trusted networks only and disable remote administration if enabled.
