Description

The version of Cisco SD-WAN vManage software installed on the remote host is affected by an information disclosure vulnerability as referenced in the cisco-sa-vmanwebid-5QWMcCvt advisory.

- A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying filesystem of the device. The vulnerability is due to insufficient file scope limiting.
