Descriptions

Dell EMC NetWorker, versions 18.x, 19.1.x, 19.2.x 19.3.x, 19.4, and 19.4.0.1 contain an Improper Certificate Validation vulnerability in the client (NetWorker Management Console) components which uses SSL encrypted connection in order to communicate with the application server. An unauthenticated attacker in the same network collision domain as the NetWorker Management Console client could potentially exploit this vulnerability to perform man-in-the-middle attacks to intercept and tamper the traffic between the client and the application server.

Dell EMC NetWorker, versiones 18.x, 19.1.x, 19.2.x 19.3.x, 19.4 y 19.4.0.1, contienen una vulnerabilidad de Comprobación de Certificados Inapropiada en los componentes del client (consola de gestión de NetWorker) que usa la conexión cifrada SSL para comunicarse con el servidor de aplicaciones. Un atacante no autenticado en el mismo dominio de colisión de red que el cliente de la Consola de administración de NetWorker podría explotar potencialmente esta vulnerabilidad para llevar a cabo ataques de tipo man-in-the-middle para interceptar y manipular el tráfico entre el cliente y el servidor de aplicaciones
