Description

Tomcat8 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.

For Debian 8

For Debian 8 'Jessie', this problem has been fixed in version
8.0.14-1+deb8u16.

We recommend that you upgrade your tomcat8 packages.
