CVE-2017-16314
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_sonos, at 0x9d01c1cc, the value for the `s_speaker` key is copied using `strcpy` to the buffer at `$sp+0x2b0`.This buffer is 32 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 confidenceA stack-based buffer overflow vulnerability exists in the PubNub message handler for the 'cc' channel of Insteon Hub firmware 1012. The cmd s_sonos function uses unbounded strcpy to copy the s_speaker key value into a 32-byte fixed buffer at stack position $sp+0x2b0, allowing overflow and arbitrary data overwrite with 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.
-
Confirm device is Insteon HubIdentify the device model in your environment inventory or network discovery. This vulnerability applies only to Insteon Hub hardware.Affected if The device is not an Insteon Hub model.
-
Check installed firmware versionRetrieve the firmware version running on the Insteon Hub device. Consult your device documentation for the appropriate command or web interface to query the current firmware version.Affected if The installed firmware version is 1012.
-
Verify PubNub integration is activeCheck if the PubNub cloud messaging service is enabled or configured on the Insteon Hub. This is typically done through the Insteon app or hub settings interface.Affected if PubNub integration is enabled on the device.
-
Confirm cc channel is configuredInspect the PubNub channel configuration on the hub to determine whether the 'cc' channel is subscribed or active for messaging.Affected if The 'cc' channel is actively subscribed or configured in the PubNub settings.
You are affected if you have an Insteon Hub running firmware version 1012 with PubNub enabled and the cc channel actively configured.
Generated from the published advisory. Verify against your own configuration.
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 unsafe strcpy with bounded string functions (strncpy/strlcpy) and implement input length validation for the s_speaker parameter; deploy updated firmware to all Insteon Hub devices.
