Name of the Vulnerable Software and Affected Versions
Insteon Hub version 1012
Description
The issue concerns buffer overflow vulnerabilities in the PubNub message handler for the "cc" channel. Specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow, overwriting arbitrary data. This can be triggered by sending an authenticated HTTP request. Specifically, in the
cmd s b, the value for the val key is copied using strcpy to a 32-byte buffer at $sp+0x2b0, and sending data longer than 32 bytes will cause a buffer overflow.Recommendations
For Insteon Hub version 1012, as a temporary workaround, consider restricting access to the PubNub message handler for the "cc" channel to minimize the risk of exploitation. Avoid using the
val key in the affected command until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
