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. 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 b, at 0x9d0165c0, the value for the id key is copied using strcpy to the buffer at $sp+0x270. This buffer is 16 bytes large, and 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 values to minimize the risk of exploitation. Update the firmware to a version that fixes this issue, if available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
