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.

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 confidence

Authenticated command injection vulnerability in multiple NETGEAR router models. An authenticated attacker can inject arbitrary OS commands through a web interface parameter, potentially gaining full device control.

MitigationUpdate affected NETGEAR devices to the specified firmware versions provided in the advisory. If patching is not possible, restrict administrative web interface access to trusted networks or disable remote management.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 router model
    Locate the model number on the device label or log into the web admin interface and check the status or router info page
    Affected if Model is D3600, D6000, D6100, D6200, D6220, D6400, D7000, or D7800
  2. Check installed firmware version
    In the router web admin interface, navigate to Administration > Firmware Update or Router Status page to view the current firmware version
    Affected if Firmware version is below the threshold for your specific model (D3600/D6000: 1.0.0.67, D6100: 1.0.0.56, D6200: 1.1.00.24, D6220: 1.0.0.32, D6400: 1.0.0.66, D7000: 1.0.1.52 or 1.0.0.44, D7800: 1.0.1.30)
  3. Verify web admin interface accessibility
    Determine if the router management web interface is accessible from external networks or untrusted devices
    Affected if Remote management is enabled or the admin interface is exposed beyond the local trusted network

You are affected if you own one of the listed NETGEAR models and your firmware version is below the specified threshold and the web admin interface is accessible to untrusted users.

Generated from the published advisory. Verify against your own configuration.
