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 grp key is copied using strcpy to a buffer, 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 commands sent through the PubNub service to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
