CVE-2018-3778 Open this link in a new tabHow to fix?
Upgrade aedes to version 0.35.1 or higher.
Overview
aedes is a Barebone MQTT server that can run on any stream server.
Affected versions of this package are vulnerable to Improper Authorization. A user can connect and subscribe to "will" from a client.
From another client, a user may connect with a last will message with topic "will". Then by sending message to "test", the connection will break (because of authorization failure).
Breaking the connection will trigger the LWT, and thus sends a message to will, which can be seen in the other client.
