Name of the Vulnerable Software and Affected Versions Insteon Hub version 1012

Description Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub. Specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. In cmd s net, at 0x9d01815c, the value for the ip key is copied using strcpy to the buffer at $sp+0x2d0. This buffer is 100 bytes large, sending anything longer will cause a buffer overflow.

Recommendations As a temporary workaround, consider restricting access to the PubNub message handler for the "cc" channel until a patch is available. Avoid sending authenticated HTTP requests with long commands to the Insteon Hub until the issue is resolved. Restrict the use of the ip key in the cmd s net to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
