4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in KaiBB, which 
can be exploited by malicious people to conduct cross-site scripting 
attacks.

Input passed via the "Referer" header to index.php and acp/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 context of an affected site.

Successful exploitation requires that the victim uses a browser that 
does not URL-encode the request (e.g. Internet Explorer 6).

A fix is not currently available.
