VERIFY ADVISORY:
http://secunia.com/advisories/31630/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
AWStats Totals 1.x
http://secunia.com/product/19657/

DESCRIPTION:
Emory University has reported some vulnerabilities in AWStats Totals,
which can be exploited by malicious people to conduct cross-site
scripting attacks or to compromise a vulnerable system.

1) Input passed via the "month" and "year" parameters is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.  

2) Input passed via the "sort" parameter to the "multisort()"
function is not properly sanitised before being used to generate PHP
code. This can be exploited to execute arbitrary PHP commands by
constructing specially crafted "sort" parameters.

The vulnerabilities are reported in versions prior to 1.15.

SOLUTION:
Update to version 1.15.
