6.3Defect ID: PAN-321573
( HA Active-Active firewalls only ) Fixed an issue where High Availability (HA) session synchronization did not occur between the active primary and secondary firewalls, which prevented sessions from properly synchronizing across the HA pair. This occurred after a firewall upgrade. With this fix, HA session synchronization between the active primary and secondary firewalls was restored.
6.3Defect ID: PAN-317598
( Firewalls in active/active HA configurations only ) Fixed an issue where NAT failures occurred due to the IP pool not releasing unused resources in the Active Secondary firewall. This occurred because the secondary firewall attempts to release a Persistent DIPP NATed port that was originally allocated by the NAT policy from first firewall, leading to a ownership mismatch during the session teardown process.
6.3Defect ID: PAN-304195
Fixed an issue on the firewall where performing a private data reset caused device telemetry to stop working. This issue also occurred after performing a factory reset and then running the CLI command set system ztp disable .
6.3Defect ID: PAN-292752
Fixed an issue where a command injection vulnerability could occur due to improper input sanitization.
6.3Defect ID: PAN-307773
Fixed an issue on Panorama where enabling Post-Quantum Pre-Shared Key (PPK) within an IKE Gateway profile that was configured as a part of a template stack failed or was inconsistent when attempted via the web interface, even when the keys were properly configured.
