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 event, at 0x9d01edb8, the value for the s raw key is copied using strcpy to the buffer at $sp+0x10. This buffer is 244 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. Restrict the length of data sent to the buffer at $sp+0x10 to prevent buffer overflow. Avoid using the s raw key in the cmd s event until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
