Description Andrej Nemec 2016-02-23 05:59:45 EST
Tomcat provides several session persistence mechanisms. The
StandardManager persists session over a restart. The PersistentManager
is able to persist sessions to files, a database or a custom Store. The
Cluster implementation persists sessions to one or more additional nodes
in the cluster. All of these mechanisms could be exploited to bypass a
security manager. Session persistence is performed by Tomcat code with
the permissions assigned to Tomcat internal code. By placing a carefully
crafted object into a session, a malicious web application could trigger
the execution of arbitrary code.
