Summary

A denial-of-service (DoS) vulnerability in the Advanced DNS Security (ADNS) feature of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker to initiate system reboots using a maliciously crafted packet. Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode. Cloud NGFW and Prisma Access® are not impacted by this vulnerability.
