|
|
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.
