Multiple 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.

Security readout for executives and security teams

Plain-English summary

CVE-2017-16287 affects Insteon Hub firmware 1012. An authenticated attacker can send crafted PubNub-based commands that overflow a small memory buffer, potentially compromising confidentiality, integrity, and availability of the hub.

Executive priority

Treat this as high priority where Insteon Hubs are deployed. The vulnerable component can affect a physical-control gateway, but urgency depends on confirmed device presence and whether supported vendor remediation exists.

Technical view

The issue is a stack-based buffer overflow in the Insteon Hub PubNub message handler for the "cc" channel. In cmd s_time, the `dstend` value is copied with `strcpy` into a 16-byte stack buffer, enabling overwrite of adjacent stack data.

Likely exposure

Exposure is likely limited to organizations or homes using Insteon Hub devices, especially firmware 1012. The bundle lists affected versions as not fully specified, so asset confirmation is required.

Exploitation context

The CVSS vector is network-accessible with low privileges but high complexity and no user interaction. Sources require an authenticated HTTP request. The bundle does not cite active exploitation, and KEV status is false.

Researcher notes

The strongest source detail is Talos' description of the vulnerable `dstend` copy path. Evidence is incomplete for fixed versions, broad affected version ranges, and exploitation in the wild.

Mitigation direction

  • Inventory Insteon Hub deployments and identify firmware versions.
  • Check Insteon or vendor guidance for supported firmware updates or replacement advice.
  • Restrict hub administration and cloud-linked access to trusted accounts and networks.
  • Retire or isolate affected hubs if no supported remediation is available.

Validation and detection

  • Confirm whether any Insteon Hub runs firmware 1012.
  • Review asset records for PubNub-connected Insteon Hub deployments.
  • Check vendor advisories before testing or changing production devices.
  • Review logs for unexpected authenticated hub or cloud-control activity.
