Description Preview
A stack-based buffer overflow vulnerability exists in Insteon Hub 2245-222 devices running firmware version 1012. When specially crafted commands are sent through the PubNub service, an attacker can cause a stack-based buffer overflow that overwrites arbitrary data. The vulnerability occurs at memory address 0x9d01ef24 where the value for the s_offset key is copied using strcpy to a buffer at $sp+0x2b0. Since this buffer is only 32 bytes large, sending a longer string will cause a buffer overflow. To exploit this vulnerability, an attacker needs to send an authenticated HTTP request.
Overview
The Insteon Hub 2245-222 is a home automation controller device that allows users to control Insteon-compatible devices remotely. The vulnerability affects devices running firmware version 1012. The issue is a classic stack-based buffer overflow caused by the unsafe use of strcpy() without proper bounds checking. When processing commands sent through the PubNub service, the device copies the s_offset key value to a fixed-size buffer (32 bytes) without verifying the input length. An authenticated attacker can exploit this vulnerability by sending specially crafted commands that exceed the buffer size, potentially leading to arbitrary code execution or device crashes.
Remediation
- Update the Insteon Hub firmware to the latest version if a patch is available.
- If no patch is available, consider implementing network segmentation to restrict access to the Insteon Hub from untrusted networks.
- Monitor for unusual authentication attempts or traffic patterns to the device.
- Contact Insteon support for additional security guidance or patch information.
- Consider using a firewall or other security controls to limit access to the device's management interfaces.
