CVE-2023-38924
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 DGN3500 1.1.00.37 was discovered to contain a buffer overflow via the http_password parameter at setup.cgi.
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 the Netgear DGN3500 router firmware version 1.1.00.37. The vulnerability is triggered via a specially crafted http_password parameter submitted to the setup.cgi binary, allowing potential 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.
-
Confirm device model is Netgear DGN3500Identify the router model number in the device GUI, label, or administrative interfaceAffected if The device is not a Netgear DGN3500, then it is not affected by this specific CVE
-
Check installed firmware versionAccess the router administrative interface and locate the firmware version information, typically found under Administration or Maintenance settingsAffected if The installed firmware version equals 1.1.00.37 exactly, then the device is affected by this vulnerability
-
Verify setup.cgi endpoint accessibilityDetermine if the router's web management interface is accessible from external networks (WAN) or if only LAN access is permittedAffected if Remote (WAN) access to the setup.cgi binary is enabled and the firmware version is 1.1.00.37, the device is exposed to remote exploitation
-
Test http_password parameter behaviorIf you have authorized access, observe how the http_password parameter in setup.cgi handles input lengthsAffected if The http_password parameter accepts excessively long input without proper bounds checking, confirming the buffer overflow condition exists
The device is affected only if it is a Netgear DGN3500 running firmware version 1.1.00.37 and the setup.cgi 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 dataApply the latest vendor-supplied firmware patch for the DGN3500. If no patch is available, disable remote management interfaces, restrict network access to the device, and monitor for unusual activity.
