An exploitable buffer overflow vulnerability exists in the PubNub message handler Insteon Hub 2245-222 - Firmware version 1012. Specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can send an authenticated HTTP request at At 0x9d014e84 the value for the cmd1 key is copied using strcpy to the buffer at $sp+0x280. This buffer is 16 bytes large.
