Descriptions

With MariaDB running on Windows, when local clients connect to the server over named pipes, it's possible for an unprivileged user with an ability to run code on the server machine to intercept the named pipe connection and act as a man-in-the-middle, gaining access to all the data passed between the client and the server, and getting the ability to run SQL commands on behalf of the connected user. This occurs because of an incorrect security descriptor. This affects MariaDB Server before 10.1.48, 10.2.x before 10.2.35, 10.3.x before 10.3.26, 10.4.x before 10.4.16, and 10.5.x before 10.5.7. NOTE: this issue exists because certain details of the MariaDB CVE-2019-2503 fix did not comprehensively address attack variants against MariaDB. This situation is specific to MariaDB, and thus CVE-2020-28912 does NOT apply to other vendors that were originally affected by CVE-2019-2503.

"Con MariaDB ejecutándose en Windows, cuando los clientes locales se conectan al servidor por medio de tuberías nombradas, es posible para un usuario no privilegiado con la habilidad de ejecutar código en la máquina del servidor interceptar la conexión de la tubería nombrada y actuar como un man-in-the-middle, consiguiendo acceso a todos los datos transmitidos entre el cliente y el servidor, y obteniendo la capacidad de ejecutar comandos SQL en nombre del usuario conectado. Esto ocurre debido a un descriptor de seguridad incorrecto. Esto afecta a MariaDB Server versiones anteriores a 10.1.48, versiones 10.2.x anteriores a 10.2.35, versiones 10.3.x anteriores a 10.3.26, versiones 10.4.x anteriores a 10.4.16 y versiones 10.5.x anteriores a 10.5.7. NOTA: este problema se presenta porque determinados detalles de la solución del CVE-2019-2503 de MariaDB no abordaron de manera integral las variantes de ataque contra MariaDB. Esta situación es específica de MariaDB,
y, por lo tanto, CVE-2020-28912 NO se aplica a otros proveedores que originalmente fueron afectados por CVE-2019-2503
