CVE-2020-9550
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 · uneditedRubetek SmartHome 2020 devices use unencrypted 433 MHz communication between controllers and beacons, allowing an attacker to sniff and spoof beacon requests remotely.
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 confidenceRubetek SmartHome 2020 devices use unencrypted 433 MHz wireless communication between controllers and beacons, allowing remote attackers within radio range to sniff sensitive beacon requests and spoof commands to control the smart home system.

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 Rubetek SmartHome devices in your environmentInventory all smart home controllers, hubs, or beacons. Look for Rubetek branded devices or devices reported to use Rubetek firmware.Affected if Rubetek SmartHome devices are present in the environment
-
Check the firmware version of Rubetek devicesAccess the device management interface or check the device firmware version through the Rubetek mobile app or administrative console. Look for a firmware version labeled as '2020'.Affected if The firmware version equals 2020
-
Verify 433 MHz wireless communication is in useCheck the device configuration or technical specifications. Determine whether the devices are configured to use 433 MHz radio frequency for controller-to-beacon communication. This may be visible in wireless settings or device pairing menus.Affected if 433 MHz communication is enabled or configured for device communication
-
Confirm encryption is not applied to wireless communicationsInspect the wireless security settings for the 433 MHz link. Verify that no encryption (such as AES-128, Z-Wave S2, or similar) is enabled or available for the 433 MHz communication channel.Affected if The 433 MHz wireless link has no encryption enabled or available
You are affected if you have Rubetek SmartHome devices running firmware version 2020 that use unencrypted 433 MHz wireless communication for controller-beacon interactions.

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.
From vendor dataMigrate to encrypted wireless protocols (such as Z-Wave S2, Zigbee with AES-128, or similar) and implement application-layer authentication for beacon communications; if hardware cannot support encrypted protocols, replace with devices that support secure communication standards.
