NetScreen Firewall is a network appliance used to secure against intruders and various types of attacks to a network. NetScreen has a Web administrative Interface (WebUI) used to configure and set the firewall settings.

It is possible to cause a denial of service in NetScreen Firewall. Requesting an unusually long URL to WebUI listening on default port 80, will cause the firewall to crash. A restart of the service is required in order to gain normal functionality. 

Once the input URL is longer than 1220 bytes=A3=ACNetScreen firewall= will crash:

$echo -e "GET /`perl -e 'print "A"x1220'` HTTP/1.0\n\n"|nc= netscreen_firewall 80

Exploit Public

- 漏洞描述

Netscreen contains a flaw that allows a remote attacker to crash the WebUI interface. The issue is due to the native web server not properly handling overly large requests. If an attacker provides a 1220+ string in a GET request, the firewall will crash, causing the firewall to stop passing/monitoring traffic.
