Описание
MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.27, 10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1, a high-privileged MariaDB user could've used wsrep_sst_receive_address or wsrep_sst_donor global system variables to execute shell commands as the uid of the mariadbd process on the galera joiner node. This issue has been patched in versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2.
A flaw was found in MariaDB server. A high-privileged MariaDB user could exploit this vulnerability by manipulating specific global system variables, namely wsrep_sst_receive_address or wsrep_sst_donor. This manipulation could allow the user to execute arbitrary shell commands as the user ID of the mariadbd process on a galera joiner node. The primary impact of this flaw is arbitrary code execution.
Отчет
This Important flaw in MariaDB server allows a high-privileged database user to achieve arbitrary code execution on a Galera joiner node. By manipulating specific global system variables, an attacker can execute shell commands as the mariadbd process user, significantly escalating privileges within the system. This risk is present in Red Hat products utilizing MariaDB with Galera Cluster deployments.
