CVE-2017-16304

Severity CVSS v4.0:
Pending analysis
Type:
CWE-121 Stack-based Buffer Overflow
Publication date:
11/01/2023
Last modified:

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 sn_ex, at 0x9d01ae40, the value for the `d` key is copied using `strcpy` to the buffer at `$sp+0x334`.This buffer is 100 bytes large, sending anything longer will cause a buffer overflow.
