The manipulation leads to denial of service. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-221147.
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 denial of service vulnerability exists in the web management interface of Netgear WNDR3700v2 router firmware version 1.0.1.14 (VDB-221147). Remote attackers can exploit unknown manipulations of the web interface to cause the device to become unresponsive, potentially through malformed requests or resource exhaustion.

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 administrative interface to confirm the exact model is Netgear WNDR3700v2Affected if The device is a Netgear WNDR3700v2
-
Check the installed firmware versionLog into the web management interface and navigate to the Firmware Update or Status page, or use the router's diagnostic interface to display the firmware versionAffected if The firmware version is 1.0.1.14
-
Confirm web management interface accessibilityVerify whether the router's HTTP/HTTPS management interface is reachable from the network. This can be done by attempting to access the router's IP address on ports 80 or 443 from relevant network segmentsAffected if The web management interface is exposed to network segments where untrusted users can reach it
-
Look for signs of device unresponsivenessTest router accessibility by pinging the device IP and attempting to access the web interface. Check if the device fails to respond to requests or displays error messages related to resource exhaustionAffected if The device becomes unresponsive or exhibits degraded performance when the web interface is accessed
You are affected if you have a Netgear WNDR3700v2 router running firmware version 1.0.1.14 with its web management interface accessible to network attackers

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 dataCheck Netgear for available firmware updates; if no patch exists, consider network-level access restrictions to the management interface or device replacement. Monitor for available security patches from the vendor.
