CVE-2017-5251
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 · uneditedIn version 1012 and prior of Insteon's Insteon Hub, the radio transmissions used for communication between the hub and connected devices are not encrypted.
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 · moderate confidenceInsteon Hub versions 1012 and prior use unencrypted radio frequency (RF) transmissions for communication with paired devices. An attacker within radio range can intercept, decode, and potentially replay commands sent between the hub and connected devices, leading to confidentiality compromise and potential integrity violations.
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 you have an Insteon Hub deviceIdentify the device model in your network inventory or physical device label. This vulnerability applies only to Insteon Hub products, not other Insteon devices.Affected if The device is not an Insteon Hub product
-
Check the installed firmware versionAccess the Insteon Hub firmware version through the device administration interface, mobile app, or device documentation. Look for a version number labeled as firmware, software, or hub version.Affected if Unable to retrieve a firmware version number for comparison
-
Compare your firmware version to the affected rangeIf you obtained a firmware version number, verify whether it is 1012 or any lower version number. Versions are typically listed as three or four digit numbers.Affected if Firmware version is 1012 or lower (for example: 1012, 1011, 1005, 101, etc.)
-
Verify the RF communication is in useConfirm the Insteon Hub is actively controlling devices via RF (radio frequency) - this includes most Insteon dimmers, switches, sensors, and thermostats paired directly to the hub without a dual-band bridge.Affected if The hub uses RF-enabled Insteon devices and the firmware is 1012 or prior
You are affected if you have an Insteon Hub running firmware version 1012 or lower that communicates with paired devices using unencrypted RF transmissions.

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 dataUpgrade the Insteon Hub to a patched firmware version if available; if no patch exists, consider network segmentation or device replacement to mitigate exposure of unencrypted RF communications.
