CVE-2022-43485Network attack vector

JWT claim manipulation via predictable signing keys

Published May 30, 2023 · Updated Jan 9, 2025

Insufficient randomness in Honeywell OneWireless 322.1 allows remote authenticated users to manipulate claims in a client's JWT token. The WDM generates JWT signing keys with insufficiently random values, allowing token claims to be changed while retaining an accepted signature. Exploitation requires high privileges and user interaction and affects integrity by enabling unauthorized claim changes.
