CWE-120Published: January 12, 2023· Updated: Jun 17, 2026

8.5

CVSS v3.1

Official Description

Multiple exploitable buffer overflow vulnerabilities exists in the PubNub message handler for the "control" channel of Insteon Hub running firmware version 1012. Specially crafted replies received from the PubNub service can cause buffer overflows on a global section overwriting arbitrary data. An attacker should impersonate PubNub and answer an HTTPS GET request to trigger this vulnerability. The `strcpy` at [18] overflows the buffer `insteon_pubnub.channel_al`, which has a size of 16 bytes.

Technical Analysis

CVE-2017-14454 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 complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.5.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
