DESCRIPTION:
Kiki has discovered a vulnerability in Jax Guestbook, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "page" parameter in admin/guestbook.admin.php is
not properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in an
administrators browser session in context of an affected site.

The vulnerability has been confirmed in version 3.50. Other versions
may also be affected.

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