CVE-2021-45585
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 · uneditedCertain NETGEAR devices are affected by command injection by an authenticated user. This affects RBK752 before 3.2.16.6, RBR750 before 3.2.16.6, RBS750 before 3.2.16.6, RBK852 before 3.2.16.6, RBR850 before 3.2.16.6, and RBS850 before 3.2.16.6.
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 confidenceAuthenticated command injection vulnerability in NETGEAR Orbi mesh WiFi systems (RBK752, RBR750, RBS750, RBK852, RBR850, RBS850) prior to firmware version 3.2.16.6 allows an attacker with valid credentials to execute arbitrary commands on the underlying operating system through insufficient input sanitization.

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 Orbi device modelLocate the model number on the device label or log into the router admin interface (typically at 192.168.1.1) and view the device information pageAffected if The model is one of: RBK752, RBR750, RBS750, RBK852, RBR850, or RBS850
-
Check the installed firmware versionIn the router admin interface, navigate to Settings > Advanced > Administration > Firmware Update or look for a Version or Firmware section under the status or advanced settingsAffected if The firmware version displayed is below 3.2.16.6 (for example, 3.2.14.2, 3.2.10.5, etc.)
-
Confirm remote administration accessCheck if remote management is enabled under Advanced > Administration > Remote Management. Also verify that default admin credentials have been changed or that the device is accessible on the local networkAffected if Remote management is exposed to the internet OR the device is on a network where untrusted users could obtain valid credentials
You are affected if your Orbi device is one of the listed models (RBK752, RBR750, RBS750, RBK852, RBR850, RBS850) AND your current firmware version is earlier than 3.2.16.6, and an attacker could obtain valid credentials to access the admin interface.
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 · scoped3.2.16.6
Update affected NETGEAR Orbi devices to firmware version 3.2.16.6 or later via the device administration interface.
Firmware version 3.2.16.6 or later for RBK752, RBR750, RBS750, RBK852, RBR850, and RBS850
- 1. Identify the specific NETGEAR Orbi mesh system model (RBK752, RBR750, RBS750, RBK852, RBR850, or RBS850) requiring the update
- 2. Download the firmware version 3.2.16.6 or later from the official NETGEAR support website (kb.netgear.com)
- 3. Access the router's web management interface by navigating to orbilogin.com or the device's IP address
- 4. Log in with administrator credentials
- 5. Navigate to the Administration > Firmware Update section
- 6. Select the option to manually upload the downloaded firmware file
- 7. Wait for the firmware upload and installation to complete - do not power off the device during this process
- 8. After reboot, verify the firmware version has been updated to 3.2.16.6 or later
