Summary

A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online.

This affects the following hardware firewall models: - PA-5400 Series firewalls - PA-7000 Series firewalls

  • Palo Alto Networks PAN-OS 9.0.17-h4, 9.1.17, 10.1.12, 10.2.8, 11.0.3, 11.1.0
