Advisory ID gitlab/maven/org.apache.activemq/activemq-core/CVE-2020-13920
Aliases CVE-2020-13920
Summary Improper Authentication 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 a user connects.
