The remote host is running a version of phpBB older than 2.0.10.

phpBB contains a flaw that allows a remote cross site scripting attack. 
This flaw exists because the application does not validate user-supplied 
input in the 'search_author' parameter.

This version is also vulnerable to a HTTP response splitting vulnerability
which permits the injection of CRLF characters in the HTTP headers.

Solution : Upgrade to 2.0.10 or later
Risk factor : Medium";
