8.1.x prior to 8.1.14 or 9.0.x prior to 9.0.7 or 9.1.x prior to 9.1.1. It is, therefore, affected by a vulnerability.

  - An external control of filename vulnerability in the
    command processing of PAN-OS allows an authenticated
    administrator to delete arbitrary system files affecting
    the integrity of the system or causing denial of service
    to all PAN-OS services. This issue affects: All versions
    of PAN-OS 7.1; PAN-OS 8.1 versions before 8.1.14; PAN-OS
    9.0 versions before 9.0.7; PAN-OS 9.1 versions before
    9.1.1. (CVE-2020-2003)

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