Vulnerability Description
A vulnerability in the session management system of the Cisco Catalyst SD-WAN Manager multi-tenant feature could allow an authenticated, remote attacker to access another tenant that is being managed by the same Cisco Catalyst SD-WAN Manager instance. This vulnerability requires the multi-tenant feature to be enabled. This vulnerability is due to insufficient user session management within the Cisco Catalyst SD-WAN Manager system.
