A flaw was found in MariaDB, which can lead to SQL injection and privilege escalation. The SHOW CREATE SERVER and SHOW CREATE USER commands, as well as the mariadb-dump utility, do not properly quote identifiers and values when serializing SQL data. An authenticated, low-privileged attacker can exploit this issue by creating database objects with crafted identifiers or values to embed malicious commands into the generated SQL output. When the exported dump or output is subsequently executed, the injected SQL statements run with the privileges of the user applying the data.
