Detail
A vulnerability in the Event Management Service daemon (emsd) of Cisco IOS XR routers, could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the 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 allow the attacker to crash the device in such a manner that manual intervention is required to recover. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
