solutions: This issue is fixed in PAN-OS 8.1.13, PAN-OS 9.0.7 and all later versions.
workarounds: These issues affect the management interface of PAN-OS and are strongly mitigated by following best practices for securing the PAN-OS management interface. Our best practices guidelines reduce the exposure of the management interface to potential attackers. Please review the Best Practices for Securing Administrative Access in the PAN-OS 9.0 technical documentation, available at: https://docs.paloaltonetworks.com/pan-os/9-0/pan-os-admin/getting-started/best-practices-for-securing-administrative-access.html.
