Descriptions

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.

Apache ActiveMQ usa la función LocateRegistry.createRegistry() para crear el registro RMI de JMX y vincular el servidor a la entrada "jmxrmi". Es posible conectarse al registro sin autenticación y llamar al método rebind para volver a vincular jmxrmi a otra cosa. Si un atacante crea otro servidor como proxy del original y lo enlaza, efectivamente se convierte en un ataque de tipo man in the middle y es capaz de interceptar las credenciales cuando un usuario se conecta. Actualice a Apache ActiveMQ versión 5.15.12
