        This module exploits a File Upload vulnerability that lead in a RCE in
        Showtime2 module (<= 3.6.2) in CMS Made Simple (CMSMS). An authenticated
        user with "Use Showtime2" privilege could exploit the vulnerability.

        The vulnerability exists in the Showtime2 module, where the class
        "class.showtime2_image.php" does not ensure that a watermark file
        has a standard image file extension (GIF, JPG, JPEG, or PNG).
