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 sn exw, at 0x9d01b20c, the value for the id key is copied using strcpy to the buffer at $sp+0x290. This buffer is 32 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 id key values to the vulnerable Insteon Hub version. Restrict the use of the strcpy function in the cmd sn exw to prevent buffer overflows. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
