Apache ActiveMQ is vulnerable to a man-in-the-middle attack, caused by improper authentication validation when connecting to the JMX RMI registry. By creating another server to proxy the original, an attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain user credentials or further compromise the system.
