http://secunia.com/advisories/33106/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Max's Guestbook
http://secunia.com/advisories/product/20722/

DESCRIPTION:
GTADarkDude has discovered some vulnerabilities in Max's Guestbook,
which can be exploited by malicious people to conduct script
insertion attacks.

Input passed to the "name" and "email" parameters in index.php 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 the context of an affected site.

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

PROVIDED AND/OR DISCOVERED BY:
