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 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.
