CVE-2021-45514
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 · uneditedNETGEAR XR1000 devices before 1.0.0.58 are affected by command injection by an unauthenticated attacker.
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 confidenceNETGEAR XR1000 routers before firmware version 1.0.0.58 contain a command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary operating system commands on the affected device.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Confirm device model is NETGEAR XR1000Access the router web interface (typically http://192.168.1.1) and navigate to the Status or Administration page to view the device model, or check the product label on the router hardware itselfAffected if The device is a NETGEAR XR1000 router
-
Check installed firmware versionIn the router web interface, go to Administration > Firmware Update or a similar Status/Management page to view the current firmware version numberAffected if The displayed firmware version is less than 1.0.0.58 (for example, 1.0.0.54, 1.0.0.50, or any version number below 1.0.0.58)
-
Compare version to affected rangeTake the firmware version found in step 2 and compare it numerically against 1.0.0.58 - note that version numbers are compared left to rightAffected if The firmware version string begins with a number lower than 1.0.0.58, or begins with 1.0.0. but ends in a number lower than 58
If the device is a NETGEAR XR1000 router running firmware version 1.0.0.57 or lower, the device is affected by this vulnerability.

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 · scoped1.0.0.58
Upgrade NETGEAR XR1000 firmware to version 1.0.0.58 or later to remediate this vulnerability.
Firmware version 1.0.0.58 or later for NETGEAR XR1000
- 1. Identify the current firmware version of the NETGEAR XR1000 device by logging into the router web interface or checking the administration page.
- 2. Navigate to the firmware update or administration section of the router's web GUI.
- 3. Download the latest firmware version 1.0.0.58 or later from the official NETGEAR support website (kb.netgear.com).
- 4. In the router's web interface, select the option to upload/update firmware and choose the downloaded firmware file.
- 5. Wait for the firmware upload and installation to complete - do not power off the device during this process.
- 6. After the router reboots, verify the firmware version has been updated to 1.0.0.58 or later.
- 7. Confirm the vulnerability is remediated by ensuring the command injection vector is no longer accessible.
