Cross Site Scripting and Local Path Disclosure Vulnerabillity:
----------------------------------------------------------------------------
-------
The Vulnerabillity is Cross Site Scripting type. If an attacker will request
the one of following url from the server

http://<host>/perl/\<sCRIPT>alert("d")</sCRIPT>\.pl    -   Cross Site
Scripting Vulnerabillity
http://<host>/perl/<script>alert('XSS')</script>.pl          -   Cross Site
Scripting Vulnerabillity
http://<host>/perl/\/.pl                                                    
     -   cgi2perl running on the server contains Local Path Disclosure
http://<host>/servlet/webacc?User.id="><script>alert('XSS')</script>     -

   -   Cross Site Scripting Vulnerabillity

If all of these circumstances are met, an attacker may be able to exploit
this issue
via a malicious link containing arbitrary HTML and script code as part of
the hostname.
When the malicious link is clicked by an unsuspecting user, the
attacker-supplied HTML
and script code will be executed by their web client. This will occur
because the server
will echo back the malicious hostname supplied in the client's request,
without sufficiently
escaping HTML and script code.

Attacks of this nature may make it possible for attackers to manipulate web
content or to
steal cookie-based authentication credentials. It may be possible to take
arbitrary actions as the victim user.
