HIGHCVSS 7/10EPSS 1.22%

Last modified

CVE-2019-12418 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 1.22% chance of exploitation in the next 30 days.
