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 authentication bypass vulnerability in NETGEAR Orbi devices allows users connected to the local network to access the router web interface as an admin.

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
How this class of weakness works · CWE-287

The mechanism that verifies who a user is can be side-stepped or fooled, letting an attacker act as someone they're not. Everything built on top of that identity then becomes untrustworthy. Fixing it means hardening the full authentication flow, including edge cases, tokens, and secondary paths.

Recommended fix High confidence

Cbr750: 4.6.14.8 | Nbr750: 4.6.15.14 | Rbe370-Rbe374: 12.1.3.11 | Rbe770: 10.5.20.7

  1. 1. Identify your NETGEAR Orbi device model (Cbr750, Nbr750, Rbe370, Rbe371, Rbe372, Rbe373, Rbe374, or Rbe770)
  2. 2. Navigate to the NETGEAR support website and locate the firmware download page for your specific device model
  3. 3. Download the firmware version equal to or higher than the fixed version for your device: Cbr750 requires 4.6.14.8, Nbr750 requires 4.6.15.14, Rbe370-Rbe374 require 12.1.3.11, Rbe770 requires 10.5.20.7
  4. 4. Access your router's web interface by entering the router's IP address in a web browser
  5. 5. Navigate to the Administration > Firmware Update section
  6. 6. Select the option to upload the downloaded firmware file
  7. 7. Wait for the firmware upload and installation to complete - do not power off the device during this process
  8. 8. After the router restarts, verify the firmware version has been updated successfully
Caveat Firmware updates may temporarily disrupt network connectivity; ensure the upgrade is performed during a maintenance window
