"The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 7.1.26 or 8.0.x prior to 8.1.13 or
8.1.x prior to 8.1.13 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.

  - A buffer overflow vulnerability in the PAN-OS management
    server allows authenticated users to crash system
    processes or potentially execute arbitrary code with
    root privileges. This issue affects: PAN-OS 7.1 versions
    earlier than 7.1.26; PAN-OS 8.0 versions earlier than
    8.0.21; PAN-OS 8.1 versions earlier than 8.1.13; PAN-OS
    9.0 versions earlier than 9.0.7; PAN-OS 9.1 versions
    earlier than 9.1.1. (CVE-2020-2015)

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