'Description'=> %q{

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).
