Product:  
Netgear Gateway Router RT314/RT311

Description:    
Netgear's RT314 is a four-port gateway router targeted at the small home or small office network. 

Systems Affected:
Tested on a Netgear RT314 running firmware versions 3.24 and 3.25. Any hardware running this firmware (RT-311 also runs 
the same firmware). Any product running ZyXel-RomPager web server 3.02 or earlier is probably also vulnerable.

Problem Description:
The Netgear RT314 Gateway Router (FW v3.25) runs a web server (ZyXEL-RomPager/3.02) for easy user configuration. This 
web server is vulnerable to the standard Cross Site Scripting problems seen in multiple web servers (noted in CERT 
CA-2000-02 from two years ago).  Though it may be difficult to exploit (attacker would need to know
the internal address of the victim's router), it still opens the possibility that an attacker could gain unauthorized 
access to the router, and possibly reconfigure it to allow remote access.

To check Netgear devices for CSS, simply access the following URL in a browser:
 http://<router_ip>/<script>alert('Vulnerable')</script>
If you receive a JavaScript pop-up alert, the system is vulnerable to Cross Site Scripting.

Vendor Status:
