CVE-2017-16297: Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" chann...

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_schd, at 0x9d01a21c, the value for the `oncmd` key is copied using `strcpy` to the buffer at `$sp+0x2d0`.This buffer is 100 bytes large, sending anything longer will cause a buffer overflow.

Security readout for executives and security teams

Plain-English summary

This vulnerability affects Insteon Hub message handling and can let an authenticated attacker crash or potentially take control of the hub by sending malformed cloud-delivered commands. The business risk is highest where these hubs control physical security, automation, or building operations.

Executive priority

Treat this as high priority for environments where Insteon Hubs affect physical access, safety, or business operations. If hubs are legacy or unsupported, replacement may be more realistic than waiting for a patch.

Technical view

Talos describes multiple stack-based buffer overflows in the PubNub "cc" channel handler on Insteon Hub firmware 1012. In cmd s_schd, the oncmd value is copied with strcpy into a 100-byte stack buffer, allowing memory corruption. CVSS is 8.5 high with network reachability, low privileges, and high CIA impact.

Likely exposure

Exposure is limited to environments using Insteon Hub, specifically firmware 1012 per the Talos description. The bundle does not define the full affected version range. Risk depends on whether hubs remain deployed, cloud/PubNub control is active, and attacker authentication is possible.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires an authenticated HTTP request and specially crafted commands via PubNub, with high attack complexity but severe potential impact if successful.

Researcher notes

Evidence is strongest for firmware 1012 and the specific oncmd stack overflow described by Talos. The CVE record lists CWE-121 and high impact, but the provided bundle does not include vendor patch status, exploit-in-the-wild confirmation, or broader version mapping.

Mitigation direction

  • Inventory all Insteon Hub deployments and record firmware versions.
  • Check Insteon or vendor guidance for firmware updates, replacements, or official mitigations.
  • Restrict hub administrative access to trusted accounts only.
  • Segment hubs from sensitive networks and limit unnecessary internet exposure where feasible.
  • Retire or replace unsupported hubs if no vendor fix is available.

Validation and detection

  • Confirm whether any Insteon Hub devices are still in production.
  • Verify firmware versions against the Talos-reported firmware 1012 exposure.
  • Review whether PubNub or cloud-based control remains enabled.
  • Audit hub account access and remove stale or shared credentials.
  • Review logs or automation history for unusual remote control events.

Stack-based Buffer Overflow

Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
