CVE-2020-11462

An issue was discovered in OpenVPN Access Server before 2.7.0 and 2.8.x before 2.8.3. With the full featured RPC2 interface enabled, it is possible to achieve a temporary DoS state of the management interface when sending an XML Entity Expansion (XEE) payload to the XMLRPC based RPC2 interface. The duration of the DoS state depends on available memory and CPU speed. The default restricted mode of the RPC2 interface is NOT vulnerable.

Se ha descubierto un problema en OpenVPN Access Server versiones anteriores a la versión 2.7.0 y versiones 2.8.x anteriores a la versión 2.8.3. Con la interfaz RPC2 con todas las funcionalidades activadas, es posible conseguir un estado DoS temporal de la interfaz de administración cuando se envía una carga útil XML Entity Expansion (XEE) hacia la interfaz RPC2 basada en XMLRPC. La duración del estado DoS depende de la memoria disponible y de la velocidad de una CPU. El modo restringido por defecto de la interfaz RPC2 NO es vulnerable.
