CVE-2024-52016
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, XR300 v1.0.3.78, R7000P v1.3.3.154, and R6400 v2 1.0.4.128 were discovered to multiple stack overflow vulnerabilities in the component wlg_adv.cgi via the apmode_dns1_pri and apmode_dns1_sec 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 Netgear router web interface (wlg_adv.cgi) when processing apmode_dns1_pri and apmode_dns1_sec POST parameters. Malformed input exceeding expected buffer size overwrites stack memory, causing device crash/DoS. Affected models are older Netgear routers (R8500, XR300, R7000P, R6400v2) running specific firmware versions.

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 router modelCheck the device label or web interface footer for the exact model number (R8500, XR300, R7000P, or R6400v2).Affected if Model is one of these four: R8500, XR300, R7000P, or R6400v2.
-
Check firmware versionLog into the web interface and navigate to Administration > Firmware Update or check the router status page for the firmware version number.Affected if Firmware version equals 1.0.2.160 (R8500), 1.0.3.78 (XR300), 1.3.3.154 (R7000P), or 1.0.4.128 (R6400v2).
-
Confirm web interface is enabledVerify the router HTTP/HTTPS management service is active by attempting to access the router login page over the local network.Affected if Web interface is accessible and the wlg_adv.cgi endpoint responds to requests.
-
Check for remote access exposureDetermine if the web interface is exposed to untrusted networks (WAN) by reviewing router firewall or port forwarding settings, or by testing external access to router IP.Affected if The web interface is reachable from outside the local trusted network.
A user is affected if they own one of the four listed models running exactly the specified firmware version and the router web interface is accessible.

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 dataPrimary mitigation is applying vendor firmware updates if available; if Netgear no longer supports these models, network-level filtering to restrict web interface access to trusted hosts or device replacement is required.
