The manipulation leads to command injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-221152.

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 confidence

A command injection vulnerability exists in the web interface of Netgear WNDR3700v2 router firmware version 1.0.1.14. The vulnerability allows remote attackers to execute arbitrary commands on the underlying operating system through unsanitized input in the web interface component.

MitigationApply available firmware patches from Netgear; if no patch exists, consider network segmentation to limit exposure or replace the end-of-life device. Disable remote web management if not required.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model
    Check the router label or access the web interface and look for the model number (WNDR3700v2) in the device info page
    Affected if Device is not a Netgear WNDR3700v2 - different models are not affected by this specific CVE
  2. Check firmware version
    Access router web interface, navigate to Administration or Firmware Upgrade section, or check the router label for firmware version 1.0.1.14
    Affected if Firmware version is exactly 1.0.1.14 - only this specific version is affected
  3. Verify web interface is accessible
    Attempt to access the router web interface at the default gateway IP (commonly 192.168.1.1) over HTTP
    Affected if Web interface responds - the vulnerability exists in this component
  4. Check remote web management status
    In the router web interface, navigate to Advanced > Administration > Remote Management and check if remote access is enabled
    Affected if Remote web management is enabled - this allows remote exploitation rather than requiring local network access

You are affected only if you have a Netgear WNDR3700v2 router running exactly firmware version 1.0.1.14, and the web interface is accessible (especially if remote management is enabled).
