CVSS v3.1

9.9

Critical

VectorAV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
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 ex, at 0x9d01addc, the value for the cmd2 key is copied using strcpy to the buffer at $sp+0x280. This buffer is 16 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 specially crafted commands to the Insteon Hub. Restrict the length of data sent to the buffer at $sp+0x280 to 16 bytes or less to prevent a buffer overflow. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
