CVE-2019-12418

When Apache Tomcat 9.0.0.M1 to 9.0.28, 8.5.0 to 8.5.47, 7.0.0 and 7.0.97 is
configured with the JMX Remote Lifecycle Listener, a local attacker without
access to the Tomcat process or configuration files is able to manipulate
the RMI registry to perform a man-in-the-middle attack to capture user
names and passwords used to access the JMX interface. The attacker can then
use these credentials to access the JMX interface and gain complete control
over the Tomcat instance.
