Descriptions

A vulnerability in the Event Management Service daemon (emsd) of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of gRPC requests. An attacker could exploit this vulnerability by repeatedly sending unauthenticated gRPC requests to the affected device. A successful exploit could cause the emsd process to crash, resulting in a DoS condition. Resolved in Cisco IOS XR 6.5.1 and later.

Una vulnerabilidad en el demonio de Event Management Service (emsd) del software IOS XR de Cisco, podría permitir a un atacante remoto no identificado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a un manejo inapropiado de las peticiones gRPC. Un atacante podría explotar esta vulnerabilidad al enviar repetidamente peticiones gRPC no autenticadas al dispositivo afectado. Un explotación con éxito podría causar que el proceso emsd se bloquee, resultando en una condición DoS. Resuelto en Cisco IOS XR versión 6.5.1 y posteriores.
