MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.26, 10.11.1 to before 10.11.17, 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and 12.3.1, MariaDB allowed SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE without verifying the FILE privilege if the FROM clause contained only subqueries. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.
A flaw was found in MariaDB server. This vulnerability allows a low-privileged authenticated user to bypass a security control that normally restricts file operations. Specifically, the system failed to verify the necessary 'FILE' privilege when certain 'SELECT' statements, which write data to files, were executed with subqueries in their 'FROM' clause. This could enable an attacker to write unauthorized files to the server's file system, potentially leading to the disclosure of sensitive information or a denial of service by corrupting or filling disk space.
Отчет
This is an Important flaw in MariaDB server that allows a low-privileged authenticated database user to bypass the 'FILE' privilege check. By crafting specific SELECT ... INTO OUTFILE or SELECT ... INTO DUMPFILE statements with subqueries, an attacker can write arbitrary files to the server's file system. This could lead to data corruption, information disclosure, or a denial of service on affected Red Hat products where MariaDB is deployed.
