The remote PAN-OS host is affected by vulnerability


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 8.1.12 or 8.1.x prior to 8.1.12 or 9.0.x prior to 9.0.6. It is, therefore, affected by a vulnerability.

- An authentication bypass vulnerability in Palo Alto Networks PAN-OS Panorama proxy service allows an unauthenticated user with network access to Panorama and the knowledge of the Firewalls serial number to register the PAN-OS firewall to register the device.
After the PAN-OS device is registered, the user can further compromise the PAN-OS instances managed by Panorama. 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 8.1.12; PAN-OS 9.0 versions earlier than 9.0.6. (CVE-2020-2018)

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