CVE-2021-1234
"Cisco SD-WAN vManage Cluster Management Interface Authentication Bypass"
Description
A vulnerability in the cluster management interface of Cisco SD-WAN vManage Software could allow an unauthenticated, remote attacker to view sensitive information on an affected system. To be affected by this vulnerability, the vManage software must be in cluster mode. This vulnerability is due to the absence of authentication for sensitive information in the cluster management interface. An attacker could exploit this vulnerability by sending a crafted request to the cluster management interface of an affected system. A successful exploit could allow the attacker to view sensitive information on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
