TITLE

Cisco Nexus 9000 Series Fabric Switch Vulnerability in

Trust: 0.8

sources: JVNDB: JVNDB-2021-004262

DESCRIPTION

A vulnerability with the Border Gateway Protocol (BGP) for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an unauthenticated, remote attacker to cause a routing process to crash, which could lead to a denial of service (DoS) condition. This vulnerability is due to an issue with the installation of routes upon receipt of a BGP update. An attacker could exploit this vulnerability by sending a crafted BGP update to an affected device. A successful exploit could allow the attacker to cause the routing process to crash, which could cause the device to reload. This vulnerability applies to both Internal BGP (IBGP) and External BGP (EBGP). Note: The Cisco implementation of BGP accepts incoming BGP traffic from explicitly configured peers only. To exploit this vulnerability, an attacker would need to send a specific BGP update message over an established TCP connection that appears to come from a trusted BGP peer. Cisco Nexus 9000 Series Fabric Switch Contains an unspecified vulnerability.Denial of service (DoS) It may be put into a state. No detailed vulnerability details are currently provided
