Description

Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode. Panorama is not impacted by these vulnerabilities.

The risk of exploitation is lower for Prisma Access as it requires an authenticated user and the external network access to the dataplane interface is restricted.
