awstatstotals.php in AWStats Totals 1.0 through 1.14 allows remote attackers to execute arbitrary code via PHP sequences in the sort parameter, which is used by the multisort function when dynamically creating an anonymous PHP function.
This Metasploit module exploits an arbitrary command execution vulnerability in the AWStats Totals PHP script. AWStats Totals version v1.0 - v1.14 are vulnerable.
