SECUNIA ADVISORY ID:
SA19725

VERIFY ADVISORY:
http://secunia.com/advisories/19725/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, Exposure of system information

WHERE:
From remote

SOFTWARE:
AWStats 6.x
http://secunia.com/product/4490/

DESCRIPTION:
r0t has discovered a vulnerability in AWStats, which can be exploited
by malicious people to disclose system information and conduct
cross-site scripting attacks.

Input passed to the "config" parameter in "awstats.pl" isn't 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.

This can also be exploited to disclose the full path to the
installation by supplying an invalid "config" parameter.

The vulnerability has been confirmed in version 6.5. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.
