Description:
Lostmon has discovered some vulnerabilities in Jax Guestbook, which can be exploited by malicious people to conduct cross-site scripting attacks or disclose certain sensitive information.

1) Input passed to the "language", "gmt_ofs" and "page" parameters isn't properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.

2) Accessing the "guestbook" and "guestbook_ips2block" files directly discloses certain sensitive information (e.g. IP addresses of users who have posted ).

The vulnerabilities have been confirmed in version 3.3 and have also been reported in versions 3.1 and 3.31. Other versions may also be affected.
