CVE-2016-0714: Apache Tomcat

High severity, CVSS 8.8. EPSS: 13.1% chance of exploitation in the next 30 days.

The session-persistence implementation in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 mishandles session attributes, which allows remote authenticated users to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that places a crafted object in a session.
