DESCRIPTION:
High-Tech Bridge SA Security Research Lab has discovered a
vulnerability in I.S. Lyubinskiy Ajax Chat, which can be exploited by
malicious people to conduct cross-site scripting attacks.

Input passed to the "chat_path" parameter in ajax-chat/ajax-chat.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 context of an affected site.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled.

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