CVE-2017-16270: Buffer Overflow
First published: Wed Jan 11 2023(Updated: )
Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub running firmware version 1012. 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 0x9d01679c, the value for the `s_sonos_cmd` key is copied using `strcpy` to the buffer at `$sp+0x290`.This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.
