  - A vulnerability in the disaster recovery feature of Cisco SD-WAN vManage Software could allow an
    authenticated, remote attacker to gain unauthorized access to user credentials. This vulnerability exists
    because access to API endpoints is not properly restricted. An attacker could exploit this vulnerability
    by sending a request to an API endpoint. A successful exploit could allow the attacker to gain
    unauthorized access to administrative credentials that could be used in further attacks. (CVE-2021-1589)
