CVE-2021-27928 – MariaDB 10.2 - 'wsrep_provider' OS Command Execution

https://notcve.org/view.php?id=CVE-2021-27928

A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product. Se detectó un problema de ejecución de código remota en MariaDB versiones 10.2 anteriores a 10.2.37, versiones 10.3 anteriores a 10.3.28, versiones 10.4 anteriores a 10.4.18 y versiones 10.5 anteriores a 10.5.9; Percona Server versiones hasta el 03-03-2021; y el parche de wsrep versiones hasta el 03-03-2021 para MySQL. Una ruta de búsqueda que no es confiable conlleva a una inyección eval, en la que un usuario SUPER de la base de datos puede ejecutar comandos del Sistema Operativo después de modificar las funciones wsrep_provider y wsrep_notify_cmd. • https://www.exploit-db.com/exploits/49765 https://github.com/Al1ex/CVE-2021-27928 https://github.com/shamo0/CVE-2021-27928-POC https://github.com/LalieA/CVE-2021-27928 http://packetstormsecurity.com/files/162177/MariaDB-10.2-Command-Execution.html https://jira.mariadb.org/browse/MDEV-25179 https://lists.debian.org/debian-lts-announce/2021/03/msg00028.html https://mariadb.com/kb/en/mariadb-10237-release-notes https://mariadb.com/kb/en/mariadb-10328-release-notes https:/& • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') •
