  script_tag(name:"insight", value:"Apache ActiveMQ, a Java message broker, 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.

For Debian 9 stretch, this problem has been fixed in version 5.14.3-3+deb9u1.

We recommend that you upgrade your activemq packages.

For the detailed security status of activemq please refer to its security tracker page at: [link moved to references]
