Description Preview
Multiple exploitable stack-based buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub running firmware version 1012. An attacker can send specially crafted commands through the PubNub service that can cause a stack-based buffer overflow, overwriting arbitrary data. The vulnerability specifically occurs in the cmd s_event_alarm function at memory address 0x9d01eb44, where the value for the 's_event_delay' key is copied using 'strcpy' to a 32-byte buffer at $sp+0x2b0. When data longer than 32 bytes is sent, it causes a buffer overflow condition.
Overview
The vulnerability affects Insteon Hub devices running firmware version 1012. The issue stems from improper bounds checking in the PubNub message handler for the "cc" channel. The vulnerable code uses unsafe string copy operations (strcpy) without verifying that the destination buffer is large enough to hold the copied data. This allows an attacker to send specially crafted commands that overflow the 32-byte buffer allocated for the 's_event_delay' key value, potentially leading to arbitrary code execution or denial of service. To exploit this vulnerability, an attacker needs to send an authenticated HTTP request to trigger the overflow condition.
Remediation
- Update the Insteon Hub firmware to the latest version if a patched version is available.
- If no patch is available, consider implementing network segmentation to restrict access to the Insteon Hub from untrusted networks.
- Monitor for suspicious traffic directed to the PubNub service interface of the Insteon Hub.
- Consider using a firewall or other security controls to limit access to the device's management interfaces.
- Contact Insteon support for additional guidance on mitigating this vulnerability.
