CVE-2020-14437
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.

This affects RBK752 before 3.2.15.25, RBK753 before 3.2.15.25, RBK753S before 3.2.15.25, RBR750 before 3.2.15.25, RBS750 before 3.2.15.25, RBK842 before 3.2.15.25, RBR840 before 3.2.15.25, RBS840 before 3.2.15.25, RBK852 before 3.2.15.25, RBK853 before 3.2.15.25, RBR850 before 3.2.15.25, and RBS850 before 3.2.15.25.
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 confidenceUnauthenticated command injection vulnerability in NETGEAR Orbi mesh WiFi systems (RBK752, RBK753, RBR750, RBS750, RBK842, RBR840, RBS840, RBK852, RBK853, RBR850, RBS850) allows remote attackers to execute arbitrary commands on the underlying operating system via specially crafted network requests. The vulnerability affects firmware versions prior to 3.2.15.25.

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 (usually at 192.168.1.1) and check the device information pageAffected if The model is one of: RBK752, RBK753, RBK753S, RBR750, RBS750, RBK842, RBR840, S840, RBK852, RBR850, RBS850, or RBK853
-
Check the installed firmware versionIn the router admin interface, navigate to Settings > Advanced > Administration > Firmware Update or look for a version number displayed on the main status pageAffected if The firmware version shown is earlier than 3.2.15.25 (for example, 3.2.14.12 or any version with a number less than 3.2.15.25)
-
Confirm the device is network accessiblePing the router IP address or attempt to access the admin web interface over HTTP/HTTPS from the local networkAffected if The device responds to network requests, meaning it is reachable and the vulnerable service is active
You are affected if your Orbi device matches one of the listed models and is running firmware version 3.2.15.24 or lower.
