Summary

MariaDB server from 10.6.1 before 10.6.28, from 10.11.1 before 10.11.19, from 11.4.1 before 11.4.13, from 11.8.1 before 11.8.9, from 12.3.1 before 12.3.3 and from 13.0.1 before 13.0.2 is affected. SHOW CREATE SERVER, SHOW CREATE USER and mariadb-dump do not consistently quote identifiers and values, causing SQL injection (CWE-89). A low-privileged attacker who creates an object with crafted identifiers or values can inject SQL into output that is later applied.

Description from the CNA

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, SHOW CREATE SERVER, SHOW CREATE USER, and mariadb-dump are affected because each does not consistently quote identifiers and values when serializing SQL. A low-privileged attacker can trigger the issue when an attacker-created object with crafted identifiers or values is included in SHOW output or a dump, then create an object with crafted identifiers or values so generated SQL contains injected statements and execute attacker-injected SQL when the poisoned output is applied. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
