CVE-2017-16334
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 · uneditedMultiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub running firmware version 1012. Specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. In cmd s_event, at 0x9d01edb8, the value for the `s_raw` key is copied using `strcpy` to the buffer at `$sp+0x10`.This buffer is 244 bytes large, sending anything longer will cause a buffer overflow.
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 confidenceStack-based buffer overflow in Insteon Hub firmware 1012's PubNub message handler for the 'cc' channel. The 's_raw' key value is copied via unsafe strcpy() into a 244-byte buffer at stack pointer offset 0x10 without bounds checking, allowing overflow and potential arbitrary code execution when authenticated HTTP requests exceeding buffer capacity are sent.

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 device as an Insteon HubLocate the physical Insteon Hub device or access its administrative interface/network footprint and confirm it is an Insteon Hub model (such as the 2245-222 / 2242-222 Insteon Hub)Affected if The device is not an Insteon Hub product
-
Check the installed firmware versionAccess the Insteon Hub admin interface (typically via web browser at the device's IP address) and navigate to Settings or About to view the firmware version, or use the Insteon mobile app to check device firmware informationAffected if The firmware version is exactly 1012
-
Verify PubNub service is enabledCheck the Insteon Hub configuration settings for PubNub integration status, typically found in the Hub's web interface under Network Settings or Advanced settings, or inspect network traffic to determine if PubNub connections are being madeAffected if PubNub service is enabled and the device communicates with PubNub servers
-
Confirm access to the 'cc' PubNub channelExamine the Insteon Hub's PubNub channel configuration or inspect network traffic to verify the 'cc' channel is active and accessible for message handlingAffected if The 'cc' channel is configured and active in the PubNub integration
A user is affected if they have an Insteon Hub running exactly firmware version 1012 with PubNub service enabled and the 'cc' channel accessible for authenticated HTTP requests.

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 dataIsolate the Insteon Hub on a restricted network segment, disable PubNub service if unnecessary, and contact Insteon for a patched firmware version.
