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.
Medium [CVE-2026-0228] improper certificate validation vulnerability in PAN-OS
An improper certificate validation vulnerability in PAN-OS allows users to connect Terminal Server Agents on Windows to PAN-OS using expired certificates even if the PAN-OS configuration would not normally permit them to do so.
High [CVE-2026-0227] vulnerability in Palo Alto Networks PAN-OS software
A vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to cause a denial of service (DoS) to the firewall. Repeated attempts to trigger this issue results in the firewall entering into maintenance mode.
Critical [CVE-2024-0012 +1] PAN-OS: Authentication Bypass in the Management Web Interface (PAN-SA-2024-0015)
An authentication bypass in Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated privilege escalation vulnerabilities like CVE-2024-9474. The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines. This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software on PA-Series, VM-Series, and CN-Series firewalls and on Panorama (virtual and M-Series). Cloud NGFW and Prisma Access are not impacted by this vulnerability.
Medium [CVE-2024-9474] PAN-OS: Privilege Escalation (PE) Vulnerability in the Web Management Interface
A privilege escalation vulnerability in Palo Alto Networks PAN-OS software allows a PAN-OS administrator with access to the management web interface to perform actions on the firewall with root privileges. This issue is applicable to PAN-OS 10.1, PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software on PA-Series, VM-Series, and CN-Series firewalls and on Panorama (virtual and M-Series) and WildFire appliances. Cloud NGFW and Prisma Access are not impacted by this vulnerability.
