CVE-2017-16336

EUVD-2017-7531 · Published Jan 11, 2023

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_var, at 0x9d01eeb0, the value for the `s_value` key is copied using `strcpy` to the buffer at `$sp+0x10`.This buffer is 244 bytes large, sending anything longer will cause a buffer overflow.
