Authenticated code execution via unchecked s_aid copy
Published Jan 11, 2023 · Updated Apr 8, 2025
Stack-based buffer overflow in the Insteon Hub 1012 PubNub handler allows remote authenticated users to execute arbitrary code. The cmd s_event_alarm handler passes the attacker-controlled s_aid string to strcpy, which writes beyond a 32-byte stack buffer without checking its length. Access to the PubNub service and an authenticated HTTP request are required; successful exploitation overwrites arbitrary data and can execute code on the hub.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
