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

Information disclosure vulnerability in NETGEAR Orbi mesh WiFi systems (RBW30, RBS40V, RBK752/753/753S/754, RBR750, RBS750, RBK852/853/854, RBR850, RBS850) allowing unauthorized access to sensitive information. The specific attack vector and nature of exposed data are not detailed in the available advisory.

MitigationApply vendor-supplied firmware updates: version 2.6.1.4 or later for RBW30/RBS40V, and version 3.2.15.25 or later for RBK/RBR/RBS series devices.

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 your Orbi device model
    Locate the model number on the device label or check the admin web interface (usually at 192.168.1.1) under the Router Status or About section
    Affected if The model is one of: RBW30, RBS40V, RBK752, RBK753, RBK753S, RBK754, RBR750, or RBS750
  2. Determine the current firmware version
    In the router admin web interface, navigate to Administration > Firmware Update or Router/About page and note the displayed firmware version number
    Affected if The firmware version cannot be determined or is not visible in the admin interface
  3. Compare RBW30/RBS40V firmware to threshold
    If your model is RBW30 or RBS40V, compare your installed firmware version against 2.6.1.4 - versions below 2.6.1.4 are affected
    Affected if Your installed version is lower than 2.6.1.4 on an RBW30 or RBS40V device
  4. Compare RBK/RBR/RBS series firmware to threshold
    If your model is RBK752, RBK753, RBK753S, RBK754, RBR750, or RBS750, compare your installed firmware version against 3.2.15.25 - versions below 3.2.15.25 are affected
    Affected if Your installed version is lower than 3.2.15.25 on any of these models

You are affected if your Orbi device model matches RBW30, RBS40V, RBK752, RBK753, RBK753S, RBK754, RBR750, or RBS750 and your current firmware version is below the corresponding threshold (2.6.1.4 for RBW30/RBS40V, 3.2.15.25 for the others).

dbcve · scoped
Upgrade available Upgrade to 2.6.1.4 / 3.2.15.25 or later
Fixed in 2.6.1.43.2.15.25
Interim mitigation

Apply vendor-supplied firmware updates: version 2.6.1.4 or later for RBW30/RBS40V, and version 3.2.15.25 or later for RBK/RBR/RBS series devices.

Recommended fix High confidence

Firmware 2.6.1.4 for Rbw30/Rbs40v; Firmware 3.2.15.25 for Rbk752/Rbk753/Rbk753s/Rbk754/Rbr750/Rbs750

  1. Identify the exact model number of your NETGEAR device (Rbw30, Rbs40v, Rbk752, Rbk753, Rbk753s, Rbk754, Rbr750, or Rbs750)
  2. Navigate to the NETGEAR support page at kb.netgear.com and locate the downloads/support page for your specific model
  3. Download the firmware version 2.6.1.4 if your device is Rbw30 or Rbs40v
  4. Download the firmware version 3.2.15.25 if your device is Rbk752, Rbk753, Rbk753s, Rbk754, Rbr750, or Rbs750
  5. Access your router or mesh system's web interface (typically at routerlogin.net or 192.168.1.1)
  6. Locate the firmware update section (usually under Administration > Firmware Update or similar)
  7. Upload and apply the downloaded firmware file
  8. Wait for the device to reboot and verify the new firmware version is installed
