          This module exploits an SEH overflow in Konica Minolta FTP Server 1.00.
        Konica Minolta FTP fails to check input size when parsing 'CWD' commands, which
        leads to an SEH overflow.  Konica FTP allows anonymous access by default; valid
        credentials are typically unnecessary to exploit this vulnerability.
