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') •

CVE-2016-6664 – MySQL / MariaDB / PerconaDB 5.5.x/5.6.x/5.7.x - 'root' System User Privilege Escalation

https://notcve.org/view.php?id=CVE-2016-6664

mysqld_safe in Oracle MySQL through 5.5.51, 5.6.x through 5.6.32, and 5.7.x through 5.7.14; MariaDB; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17, when using file-based logging, allows local users with access to the mysql account to gain root privileges via a symlink attack on error logs and possibly other files. mysqld_safe en Oracle MySQL hasta la versión 5.5.51, 5.6.x hasta la versión 5.6.32 y 5.7.x hasta la versión 5.7.14; MariaDB; Percona Server en versiones anteriores a 5.5.51-38.2, 5.6.x en versiones anteriores a 5.6.32-78-1 y 5.7.x en versiones anteriores a 5.7.14-8 y Percona XtraDB Cluster en versiones anteriores a 5.5.41-37.0, 5.6.x en versiones anteriores a 5.6.32-25.17 y 5.7.x en versiones anteriores a 5.7.14-26.17, cuando usa un inicio de sesión basada en archivo, permite a usuarios locales con acceso a la cuenta mysql obtener privilegios de root a través de un ataque de enlace simbólico en errores de acceso y posiblemente otros archivos. A flaw was found in the way the mysqld_safe script handled creation of error log file. The mysql operating system user could use this flaw to escalate their privileges to root. MySQL-based databases including MySQL, MariaDB and PerconaDB are affected by a privilege escalation vulnerability which can let attackers who have gained access to mysql system user to further escalate their privileges to root user allowing them to fully compromise the system. The vulnerability stems from unsafe file handling of error logs and other files. • https://www.exploit-db.com/exploits/40679 http://legalhackers.com/advisories/MySQL-Maria-Percona-RootPrivEsc-CVE-2016-6664-5617-Exploit.html http://packetstormsecurity.com/files/139491/MySQL-MariaDB-PerconaDB-Root-Privilege-Escalation.html http://rhn.redhat.com/errata/RHSA-2016-2130.html http://rhn.redhat.com/errata/RHSA-2016-2749.html http://seclists.org/fulldisclosure/2016/Nov/4 http://www.debian.org/security/2017/dsa-3770 http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722. • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
