Every CVE for Palo Alto Networks Cloud NGFW

Exploited in the last 30 days

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.
