'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.

# This is based on jduck's tomcat_mgr_deploy.
# the tomcat_mgr_deploy o longer works for current versions of tomcat due to
# CSRF protection tokens. Also PUT requests against the /manager/html/deploy
# aren't allowed anymore.
# There is no single vulnerability associated with deployment functionality.
# Instead, the focus has been on insecure/blank/hardcoded default passwords.
