http://secunia.com/advisories/30071/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Maian Guestbook 3.x
http://secunia.com/product/18620/

DESCRIPTION:
Khashayar Fereidani has discovered some vulnerabilities in Maian
Guestbook, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Input passed to the "msg_script2" and "msg_script3" parameters in
admin/inc/footer.php is not properly sanitised before being returned
to an administrator. This can be exploited to execute arbitrary HTML
and script code in an administrator's browser session in context of
an affected site.

The vulnerabilities are confirmed in version 3.2. Other versions may
also be affected.

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