CVE-2017-14444:Buffer Overflow Vulnerability in Insteon Hub Firmware 1012 HTTP Server

Back

Description Preview

An exploitable buffer overflow vulnerability exists in the Insteon Hub running firmware version 1012. The vulnerability is present in the HTTP server implementation which incorrectly handles URL parameters during firmware update requests. This leads to a buffer overflow on a global section. An attacker can trigger this vulnerability by sending a specially crafted HTTP GET request, potentially allowing remote code execution or denial of service.

Overview

The Insteon Hub with firmware version 1012 contains a critical buffer overflow vulnerability (CWE-119) in its HTTP server component. The issue occurs specifically during the processing of firmware update requests, where the application fails to properly validate and bound-check URL parameters. When the server processes these malformed requests, it writes beyond the bounds of an allocated buffer in a global memory section. This vulnerability could allow an attacker to execute arbitrary code with the privileges of the running application or cause the device to crash, resulting in a denial of service condition. Given the nature of Insteon Hub as a home automation controller, successful exploitation could potentially grant an attacker control over connected devices.

Remediation

Users of affected Insteon Hub devices should:

  1. Update to the latest firmware version as soon as it becomes available from the manufacturer
  2. Until a patch is available, consider placing the Insteon Hub behind a properly configured firewall that restricts access to the web interface
  3. Disable remote access to the Insteon Hub if not required
  4. Monitor for unusual activity on the network that might indicate exploitation attempts
  5. Contact Insteon support for additional guidance and information on patched firmware availability
  6. Consider network segmentation to isolate IoT devices from critical systems
