CVE-2017-14454Public exploitNetwork attack vector

Code execution via unchecked alert-channel buffer copy

Published Jan 11, 2023 · Updated Apr 9, 2025

Buffer overflow in the PubNub control-channel handler in Insteon Hub firmware 1012 allows attackers to execute code via a crafted reply. The sub_9d053904 callback passes the unbounded JSON al string to strcpy, overflowing the 16-byte insteon_pubnub.channel_al global buffer. Exploitation requires impersonating PubNub after a factory reset and answering the hub's HTTPS GET request; a device crash is also demonstrated.
