Solutions

This issue is fixed in PAN-OS 8.1.20-h1, PAN-OS 9.0.14-h3, PAN-OS 9.1.11-h2, PAN-OS 10.0.8, PAN-OS 10.1.3, and all later PAN-OS versions.

This issue is fixed in Prisma Access 2.2 Preferred and all later Prisma Access versions.

Configurations

This issue is applicable only to PAN-OS firewall configurations that receive dynamic updates. You can verify that your firewall receives dynamic updates at ‘Device Deployment > Dynamic Updates' in the web interface.

Workarounds

You can disable scheduled dynamic updates for the firewall at 'Device Deployment > Dynamic Updates' in the web interface. Choosing not to receive dynamic updates will minimize your exposure to this vulnerability until you upgrade the PAN-OS firewall to a fixed version.
