        This module exploits a vulnerability found in HP Smart Storage Administrator. By
        supplying a specially crafted HTTP request, it is possible to control the
        'command' variable in function isDirectFileAccess (found in ipcelmclient.php),
        which will be used in a proc_open() function. Versions prior to HP SSA 2.60.18.0 are vulnerable.
