CVE-2017-16287
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_time, at 0x9d018f00, the value for the `dstend` key is copied using `strcpy` to the buffer at `$sp+0x270`.This buffer is 16 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 PubNub message handler for the 'cc' channel. The 's_time' command copies the 'dstend' key value using unsafe strcpy to a 16-byte stack buffer, allowing overflow and potential arbitrary code execution via authenticated HTTP requests.

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 Insteon Hub device on networkLocate Insteon Hub devices by checking for devices responding on common ports or by examining network inventory for Insteon Hub hardwareAffected if Device is an Insteon Hub with firmware 1012 and exposes the PubNub/cc channel interface
-
Check firmware versionAccess the Insteon Hub admin interface or use the device's API to query the firmware version. Typically found in the device settings or via a status endpointAffected if Firmware version is exactly 1012 (this specific version is affected; other versions are not)
-
Verify PubNub cc channel is accessibleCheck if the device exposes the PubNub message handler interface on port 8080 or 18888. Attempt to reach the cc channel endpoint or monitor network traffic to the PubNub serviceAffected if The device accepts PubNub messages on the cc channel without additional authentication layers beyond basic auth
-
Confirm s_time command processingExamine network traffic or logs for s_time command usage, or test if the device processes PubNub messages containing the s_time command with a dstend keyAffected if The device processes s_time commands from the cc channel and handles the dstend key parameter
You are affected if you have an Insteon Hub running firmware version 1012 with the PubNub cc channel interface exposed and accessible to process the s_time command with dstend key values.

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 dataReplace strcpy with bounds-checked functions (strncpy, strlcpy) and implement input length validation; if vendor patch unavailable, implement network segmentation and monitor for exploitation attempts.
