CVSS v3.1

Official Description

Specially crafted commands sent through the PubNub service in Insteon Hub 2245-222 with firmware version 1012 can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability.At 0x9d014cc0 the value for the cmd key is copied using strcpy to the buffer at $sp+0x11c. This buffer is 20 bytes large, sending anything longer will cause a buffer overflow.

Technical Analysis

CVE-2017-16252 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
