What is CVE-2017-16331?
CVE-2017-16331 is a high-severity memory corruption vulnerability in Insteon Hub Firmware, published on 11 Jan 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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_event_alarm, at 0x9d01ebd4, the value for the `s_tid` key is copied using `strcpy` to the buffer at `$sp+0x2b0`.This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.
