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.
