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 checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelCheck the device label or web interface status page to confirm the model is Netgear RAX30Affected if The device is a Netgear RAX30 router
-
Check the installed firmware versionAccess the router web interface (typically at 192.168.1.1), navigate to Administration > Firmware Update or Advanced > Administration > Router Update, and note the current firmware version displayedAffected if The firmware version is earlier than V1.0.10.94 (e.g., V1.0.10.90, V1.0.8.30, etc.)
-
Determine if file sharing feature is enabledAccess the router web interface and look for USB/Storage/File Sharing settings, typically under Advanced > USB Storage or ReadySHARE. Check if the feature is turned on and configuredAffected if The file sharing feature is enabled and an external USB drive is connected to the router
You are affected if you have a Netgear RAX30 router running firmware earlier than V1.0.10.94 with the file sharing feature enabled and accessible to authenticated users.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.0.10.94
Update NETGEAR Nighthawk WiFi6 Router firmware to version V1.0.10.94 or later. If immediate update is not possible, disable the file sharing feature until the patch can be applied.
1.0.10.94
- 1. Access the NETGEAR Nighthawk Rax30 router web interface by navigating to the router's IP address (typically 192.168.1.1) in a web browser
- 2. Log in with administrator credentials
- 3. Navigate to the Administration or Advanced settings section
- 4. Find the Firmware Update or Router Update option
- 5. Download firmware version 1.0.10.94 (or later) from NETGEAR's official support website for the Rax30 model
- 6. In the router interface, use the manual firmware upload option to select and apply the downloaded firmware file
- 7. Wait for the firmware upload and installation to complete - do not power off the router during this process
- 8. After the router restarts, verify the firmware version has been updated to 1.0.10.94 or later in the router status page
