# Overview : 
#
# ZoneAlarm is a firewall software
# package designed for Microsoft Windows 
# operating systems that blocks intrusion 
# attempts, trusted by millions, and has 
# advanced privacy features like worms, 
# Trojan horses, and spyware protection. 
# ZoneAlarm is distributed and maintained 
# by Zone Labs.http://www.zonelabs.com
#
# Details :
#
# ZoneAlarm was found vulnerable to a
# serious vulnerability leading to a
# remote Denial Of Service condition due 
# to failure to handle udp random 
# packets, if an attacker sends multiple 
# udp packets to multiple ports 0-65000, 
# the machine will hang up until the
# attacker stop flooding. 
#
# The following is a remote test done 
# under ZoneAlarm version 3.7.202 running 
# on windows xp home edition.
#
# on irc test1 joined running ZoneAlarm
# version 3.7.202 with default
# installation
#
# * test1 (test () 62 251 *** **) has joined #Hackology
#
# from a linux box :
#
# [root () mail DoS]# ping 62.251.***.**
# PING 62.251.***.** (62.251.***.**) from 
# ***.***.**.** : 56(84) bytes of data.
#
# --- 62.251.***.** ping statistics ---
# 7 packets transmitted, 0 received, 100% 
# loss, time 6017ms
#
# on irc
#
# -> [test1] PING
#
# [test1 PING reply]: 1secs
#
# Host is firewalled and up
#
# now lets try to dos
#
# --- ZoneAlarm Remote DoS Xploit
# ---
# --- Discovered & Coded By _6mO_HaCk
#
# [*] DoSing 62.251.***.** ... wait 1
# minute and then CTRL+C to stop
#
# [root () mail DoS]#
#
# after 2 minutes
#
# * test1 (test () 62 251 *** **) Quit (Ping timeout)
#
# I have made the same test on ZoneAlarm 
# Pro 4.0 Release running on windows xp
# professional and i've got the same 
# result.
#
# Exploit released : 02/09/03
#
# Vulnerable Versions : ALL
#
# Operating Systems : ALL Windows
#
# Successfully Tested on :
#
# ZoneAlarm version 3.7.202 / windows xp 
# home edition / windows 98.
#
# ZoneAlarm Pro 4.0 Release / windows xp 
# professional
#
# Vendor status : UNKOWN
#
# Solution : Shut down ZoneAlarm and wait 
# for an update.
#
# The following is a simple code written 
# in perl to demonstrate that, the code 
# is clean, it wont eat your cpu usage
# and it doesnt need to be run as root 
# but you still have to use it at your
# own risk and on your own machine or
# remotly after you get permission.
#
# Big thanx go to D|NOOO and frost for 
# providing me windows boxes with
# zonealarm for testing
