Workarounds

You can mitigate this issue by disabling decryption on your firewalls. To temporarily disable SSL Decryption, refer to the administrator’s guide for your PAN-OS software (such as PAN-OS 11.1: https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-admin/decryption/temporarily-disable-ssl-decryption) . Additionally, to ensure that decryption remains disabled after a reboot, configure a policy-based decryption exclusion that excludes all traffic from being decrypted ( https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-admin/decryption/decryption-exclusions/create-a-policy-based-decryption-exclusion) .
