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.
The file manager component has a problem where a user could upload a file of a type that does not match the list of allowable file types. This vulnerability allowed for an Admin user to upload a file that could then grant them access to the entire portal i.e. an admin user account permission escalation. 2b1af7f3a8
