CVE-2019-12418

Cuando Apache Tomcat 9.0.0.M1 hasta 9.0.28, 8.5.0 hasta 8.5.47, 7.0.0 y 7.0.97, es configurado con JMX Remote Lifecycle Listener, un atacante local sin acceso al proceso de Tomcat o a archivos de configuración es capaz de manipular el registro RMI para llevar a cabo un ataque de tipo man-in-the-middle para capturar nombres de usuario y contraseñas utilizados para acceder a la interfaz de JMX. El atacante puede usar estas credenciales para acceder a la interfaz de JMX y conseguir un control completo sobre la instancia de Tomcat.

A privilege escalation flaw was found in Tomcat when the JMX Remote Lifecycle Listener was enabled. A local attacker without access to the Tomcat process or configuration files could be able to manipulate the RMI registry to perform a man-in-the-middle attack. The attacker could then capture user names and passwords used to access the JMX interface and gain complete control over the Tomcat instance.
