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. These vulnerabilities can be triggered by sending specially crafted commands through the PubNub service, causing a stack-based buffer overflow that overwrites arbitrary data. An attacker must send an authenticated HTTP request to exploit this issue. Specifically, in the cmd g schd, the value for the grp key is copied using strcpy to a buffer located at $sp+0x1b4, which is 8 bytes large. Sending data longer than this buffer size will cause a buffer overflow.

Recommendations For Insteon Hub version 1012, consider restricting access to the PubNub message handler for the "cc" channel until a patch is available. As a temporary workaround, avoid using the grp key in the cmd g schd command to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
