CVE-2017-16252: Specially crafted commands sent through the PubNub service in Insteon Hub 2245-222 with firmware version 10...

Specially crafted commands sent through the PubNub service in Insteon Hub 2245-222 with firmware version 1012 can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability.At 0x9d014cc0 the value for the cmd key is copied using strcpy to the buffer at $sp+0x11c. This buffer is 20 bytes large, sending anything longer will cause a buffer overflow.

Security readout for executives and security teams

Plain-English summary

CVE-2017-16252 affects Insteon Hub 2245-222 firmware 1012. An authenticated attacker using the PubNub service path could trigger a memory corruption flaw that may compromise confidentiality, integrity, and availability. The source bundle does not identify a vendor patch or active exploitation evidence.

Executive priority

Treat as a high-priority legacy IoT risk where affected hubs are still deployed. Prioritize inventory, access restriction, and replacement planning if no vendor-supported fix is available.

Technical view

The flaw is a stack-based buffer overflow in handling the cmd key. Talos reports the value is copied with strcpy into a 20-byte stack buffer, allowing overwrite of adjacent data. CVSS 3.0 is 8.5 with network attack vector, high complexity, low privileges, no user interaction, and changed scope.

Likely exposure

Exposure is likely limited to environments running Insteon Hub 2245-222 with firmware version 1012, especially where authenticated PubNub-connected command paths remain available.

Exploitation context

Sources describe exploitation via an authenticated HTTP request through PubNub. The CVE is not listed as KEV in the provided bundle, and no cited source here confirms active exploitation.

Researcher notes

The strongest evidence is Talos technical reporting and the CVE record. The affected version is specific, but the provided sources do not name a patch level, mitigation bulletin, CWE mapping, or in-the-wild exploitation.

Mitigation direction

  • Inventory Insteon Hub 2245-222 devices and confirm firmware versions.
  • Check Insteon or maintainer guidance for patched firmware or replacement advice.
  • Restrict administrative and cloud-connected access to trusted users only.
  • Retire or isolate affected hubs if no supported update exists.
  • Monitor for abnormal PubNub or hub command activity.

Validation and detection

  • Confirm whether any hub is model 2245-222 running firmware 1012.
  • Review Talos advisory TALOS-2017-0483 against deployed firmware.
  • Verify who has authenticated access to the hub command path.
  • Check logs for unusual command failures or unexpected hub resets.
  • Document compensating controls if firmware remediation is unavailable.
