"According to its self-reported version, Cisco SD-WAN Viptela Software is affected by a vulnerability.

  - A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote
    attacker to retrieve arbitrary files from an affected system. This vulnerability is due to improper
    validation of parameters that are sent to the web UI. An attacker could exploit this vulnerability by
    logging in to Cisco Catalyst SD-WAN Manager and issuing crafted requests using the web UI. A successful
    exploit could allow the attacker to obtain arbitrary files from the underlying Linux file system of an
    affected system. To exploit this vulnerability, the attacker must be an authenticated user.
    (CVE-2023-20261)
