Overview
About vulnerability
Background
NATS.io is a high performance open source pub-sub distributed communication technology, built for the cloud, on-premise, IoT, and edge computing.
The nats-server provides an MQTT client interface.
Problem Description
For MQTT deployments using usercodes/passwords: MQTT passwords are incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring endpoints.
Affected Versions
Any version before v2.12.6 or v2.11.15
Workarounds
Ensure monitoring end-points are adequately secured.
Best practice remains to not expose the monitoring endpoint to the Internet or other untrusted network users.
