SHOW GRANTS FOR CURRENT_USER; SELECT * FROM mysql.user WHERE user = 'current_user'\G; Use code with caution.
In older, unpatched systems (MySQL/MariaDB around 2012), a subtle flaw in the memcmp validation allowed attackers to authenticate successfully by repeatedly trying any password. A simple Bash loop can exploit this timing/token flaw:
LOAD DATA LOCAL INFILE '/etc/passwd' INTO TABLE temp_table FIELDS TERMINATED BY '\n';
Error-based SQL injection involves injecting malicious SQL code to generate error messages that reveal sensitive information about the database. mysql hacktricks verified

The principles of MySQL hacking extend directly into cloud environments. HackTricks Cloud details how to pivot from a compromised cloud database to its entire cloud infrastructure. The core insight is that once a cloud database instance is reachable, the cloud's management plane is often less protected than the database itself.
While a direct write is ideal, defenders often place roadblocks. HackTricks notes the following constraints and clever bypasses: SHOW GRANTS FOR CURRENT_USER; SELECT * FROM mysql
When data reflection is disabled but database errors are printed to the screen, functions like EXTRACTVALUE or UPDATEXML can be leveraged to force an error containing data: ' AND EXTRACTVALUE(1, CONCAT(0x5c, (SELECT version())))-- - Use code with caution. Blind and Time-Based Injection
