Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI
registry and binds the server to the "jmxrmi" entry. It is possible to connect
to the registry without authentication and call the rebind method to rebind
jmxrmi to something else. If an attacker creates another server to proxy the
original, and bound that, he effectively becomes a man in the middle and is
able to intercept the credentials when an user connects. Upgrade to Apache
ActiveMQ 5.15.12.
