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 · unedited
Certain NETGEAR devices are affected by incorrect configuration of security settings. This affects EX3700 before 1.0.0.64, EX3800 before 1.0.0.64, EX6000 before 1.0.0.24, EX6130 before 1.0.0.16, EX6400 before 1.0.1.60, EX7000 before 1.0.0.50, EX7300 before 1.0.1.60, and WN2500RPv2 before 1.0.1.46.

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

This vulnerability involves an incorrect configuration of security settings on multiple NETGEAR wireless range extender models (EX3700, EX3800, EX6000, EX6130, EX6400, EX7000, EX7300, WN2500RPv2). The specific nature of the misconfiguration is not detailed in the available description, but it is classified as a security setting misconfiguration rather than a code-level flaw.

MitigationApply the corresponding firmware update to each affected device model before the specified version thresholds (EX3700/EX3800: 1.0.0.64, EX6000: 1.0.0.24, EX6130: 1.0.0.16, EX6400/EX7300: 1.0.1.60, EX7000: 1.0.0.50, WN2500RPv2: 1.0.0.46).

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 the exact model number
    Locate the model number on the device label or in the web management interface (typically at System > Device Information or similar). Confirm it matches one of: EX3700, EX3800, EX6000, EX6130, EX6400, EX7000, EX7300, or WN2500RPv2.
    Affected if The device is not one of these eight models, the device is not affected by this CVE.
  2. Check the installed firmware version
    Access the extender's web interface (usually at 192.168.1.250 or mywifiext.net) and navigate to the firmware version or status page. The location varies by model but is typically under Settings, System, or Device Information.
    Affected if You cannot determine the firmware version, document this limitation in your assessment.
  3. Compare firmware version against affected thresholds
    Match your model and version to the affected thresholds: EX3700/EX3800 < 1.0.0.64, EX6000 < 1.0.0.24, EX6130 < 1.0.0.16, EX6400 < 1.0.1.60, EX7000 < 1.0.0.50, EX7300 < 1.0.1.60, WN2500RP < 1.0.0.46 (note: advisory says 1.0.1.46 but mitigation says 1.0.0.46 - use the lower threshold for detection).
    Affected if The installed firmware version is below the threshold for your specific model.

Your device is affected if it is one of the eight models listed and its firmware version falls below the corresponding threshold for that model.
