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
An unauthenticated user on the local network can gain control of the router and make unauthorized changes to its operation.

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

An unauthenticated attacker on the local network can exploit this router vulnerability to gain full administrative control without any credentials, allowing complete unauthorized configuration changes to the device.

MitigationApply vendor firmware updates immediately; if unavailable, isolate the router via network segmentation/VLANs or replace with patched hardware.

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

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 check the admin interface for the exact model (Cax30, Rax30, Rax5, or Raxe300)
    Affected if Model is Netgear Cax30, Rax30, Rax5, or Raxe300
  2. Check installed firmware version
    Access the router admin web interface (typically at 192.168.1.1) and navigate to Administration > Firmware Update or check the status page for the firmware version number
    Affected if Firmware version is below 2.2.1.4 for Cax30, below 1.0.10.94 for Rax30, below 1.0.5.34 for Rax5, or below 1.0.10.72 for Raxe300
  3. Verify admin interface is accessible from LAN
    From a device connected to the router LAN (not the guest network), open a web browser and attempt to reach the router admin page (192.168.1.1 or routerlogin.net)
    Affected if The admin login page loads without authentication, indicating the management interface is exposed to the local network

You are affected if you have a Netgear Cax30, Rax30, Rax5, or Raxe300 router running firmware versions lower than 2.2.1.4, 1.0.10.94, 1.0.5.34, or 1.0.10.72 respectively, and the admin interface is accessible from your local network.

Recommended fix High confidence

Cax30: 2.2.1.4+ | Rax30: 1.0.10.94+ | Rax5: 1.0.5.34+ | Raxe300: 1.0.10.72+

  1. 1. Identify the specific Netgear router model (Cax30, Rax30, Rax5, or Raxe300) from the affected devices
  2. 2. Visit the Netgear support website (support.netgear.com) and locate the firmware download page for your router model
  3. 3. Download the firmware version 2.2.1.4 or later for Cax30, version 1.0.10.94 or later for Rax30, version 1.0.5.34 or later for Rax5, or version 1.0.10.72 or later for Raxe300
  4. 4. Open a web browser and access the router's admin interface by entering the router's local IP address (commonly 192.168.1.1)
  5. 5. Log into the router administration panel with administrator credentials
  6. 6. Navigate to the 'Advanced' > 'Administration' > 'Firmware Update' or similar section
  7. 7. Click 'Choose File' or 'Browse' and select the downloaded firmware file
  8. 8. Click 'Upload' or 'Update' to install the new firmware
Caveat Firmware updates typically retain settings, but backup router configuration before updating as a precaution
