"The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 8.1.14 or 8.0.x prior to 8.1.14 or
8.1.x prior to 8.1.14 or 9.0.x prior to 9.0.7. It is, therefore, affected by a vulnerability.

  - An external control of filename vulnerability in the SD
    WAN component of Palo Alto Networks PAN-OS Panorama
    allows an authenticated administrator to send a request
    that results in the creation and write of an arbitrary
    file on all firewalls managed by the Panorama. In some
    cases this results in arbitrary code execution with root
    permissions. This issue affects: All versions of PAN-OS
    7.1; PAN-OS 8.1 versions earlier than 8.1.14; PAN-OS 9.0
    versions earlier than 9.0.7. (CVE-2020-2009)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
