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 CSRF. This affects EX6100 before 1.0.2.16_1.1.130, EX6100v2 before 1.0.1.70, EX6150v2 before 1.0.1.54, EX6200v2 before 1.0.1.50, EX6400 before 1.0.1.60, EX7300 before 1.0.1.60, and WN3000RPv3 before 1.0.2.44.

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

Cross-Site Request Forgery (CSRF) vulnerability in multiple NETGEAR wireless range extenders (EX6100, EX6100v2, EX6150v2, EX6200v2, EX6400, EX7300, WN3000RPv3) allows remote attackers to perform unauthorized administrative actions by tricking authenticated users into visiting malicious web pages.

MitigationUpdate affected devices to the latest firmware versions provided by NETGEAR. If updates are unavailable, avoid browsing untrusted sites while logged into the device admin interface and consider network segmentation.

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 NETGEAR range extender model on your network
    Locate the device physically or check your network devices list for models EX6100, EX6100v2, EX6150v2, EX6200v2, EX6400, EX7300, or WN3000RPv3
    Affected if The device is one of these seven models and is present on your network
  2. Check the installed firmware version
    Access the device admin interface (typically http://www.mywifiext.com or http://192.168.1.250) and navigate to Settings > Firmware Update, or check the web interface footer for the version number
    Affected if The firmware version is lower than 1.0.2.16 for EX6100, lower than 1.0.1.54 for EX6150, lower than 1.0.1.50 for EX6200, lower than 1.0.1.60 for EX6400 or EX7300, or lower than 1.0.2.44 for WN3000RP
  3. Verify the web admin interface is accessible
    Attempt to reach the device admin page via a browser on the same network segment
    Affected if The web interface is reachable and responds, meaning an authenticated session could potentially be exploited via CSRF
  4. Confirm remote management is enabled (if applicable)
    In the device web interface, check Settings > Remote Management or Administration > Remote Management settings
    Affected if Remote management is enabled and the interface is accessible from outside the local network, increasing the attack surface

You are affected if you have any of the listed NETGEAR range extender models running firmware versions below the specified thresholds and the web admin interface is accessible on your network.
