According to its self-reported version, Cisco SD-WAN Viptela Software is affected by an information disclosure vulnerability due to absence of authentication to view sensitive information. An unauthenticated, remote attacker can exploit this, by sending a crafted request to the cluster management interface of an affected system, to view sensitive information. This vulnerability only affects vManage systems in cluster mode.
Please see the included Cisco BID and Cisco Security Advisory for more information.
