A null pointer dereference in Palo Alto Networks PAN-OS software on PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series hardware platforms when Decryption policy is enabled allows an unauthenticated attacker to crash PAN-OS by sending specific traffic through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode.

Palo Alto Networks VM-Series, Cloud NGFW, and Prisma Access are not affected.

This issue only affects PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series running these specific versions of PAN-OS:

10.2.7-h12 10.2.8-h10 10.2.9-h9 10.2.9-h11 10.2.10-h2 10.2.10-h3 10.2.11 10.2.11-h1 10.2.11-h2 10.2.11-h3 11.1.2-h9 11.1.2-h12 11.1.3-h2 11.1.3-h4 11.1.3-h6 11.2.2 11.2.2-h1

A denial-of-service (DoS) vulnerability in the Simple Certificate Enrollment Protocol (SCEP) authentication 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 is not affected by this vulnerability. Prisma® Access software is proactively patched and protected from this issue.

When configured using SAML, a session fixation vulnerability in the GlobalProtect™ login enables an attacker to impersonate a legitimate authorized user and perform actions as that GlobalProtect user. This requires the legitimate user to first click on a malicious link provided by the attacker.

The SAML login for the PAN-OS® management interface is not affected. Additionally, this issue does not affect Cloud NGFW and all Prisma® Access instances are proactively patched.

An unauthenticated file deletion vulnerability in the Palo Alto Networks PAN-OS management web interface enables an unauthenticated attacker with network access to the management web interface to delete certain files as the “nobody” user; this includes limited logs and configuration files but does not include system files.

The attacker must have network access to the management web interface to exploit this issue. You can greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended critical deployment guidelines (https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431).

This issue does not affect Cloud NGFW or Prisma Access software.

A command injection vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to bypass system restrictions in the management plane and delete files on the firewall.

A vulnerability in the Palo Alto Networks PAN-OS software enables an authenticated admin on the PAN-OS CLI to read arbitrary files.

The attacker must have network access to the management interface (web, SSH, console, or telnet) and successfully authenticate to exploit this issue. You can greatly reduce the risk of this issue by restricting access to the management interface to only trusted users and internal IP addresses according to our recommended critical deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .

This issue does not affect Cloud NGFW or Prisma Access.

A Denial of Service (DoS) vulnerability in Palo Alto Networks PAN-OS software causes the firewall to unexpectedly reboot when processing a specially crafted LLDP frame sent by an unauthenticated adjacent attacker. Repeated attempts to initiate this condition causes the firewall to enter maintenance mode.

This issue does not apply to Cloud NGFWs or Prisma Access software.
