A memory corruption vulnerability in Palo Alto Networks PAN-OS software allows an unauthenticated attacker to crash PAN-OS due to a crafted packet 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.

A Denial of Service (DoS) vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software enables an unauthenticated attacker to render the service unavailable by sending a large number of specially crafted packets over a period of time. This issue affects both the GlobalProtect portal and the GlobalProtect gateway.

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

An authenticated file deletion vulnerability in the Palo Alto Networks PAN-OS® software enables an authenticated 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 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 affects Cloud NGFW. However, this issue does not affect Prisma® Access software.

An improper certificate validation vulnerability in Palo Alto Networks PAN-OS software enables an authorized user with a specially crafted client certificate to connect to an impacted GlobalProtect portal or GlobalProtect gateway as a different legitimate user. This attack is possible only if you "Allow Authentication with User Credentials OR Client Certificate."

Using the AES-128-CCM algorithm for IPSec on certain Palo Alto Networks PAN-OS® firewalls (PA-7500, PA-5400, PA-5400f, PA-3400, PA-1400, and PA-400 Series) leads to unencrypted data transfer to devices that are connected to the PAN-OS firewall through IPSec.

This issue does not affect Cloud NGFWs, Prisma® Access instances, or PAN-OS VM-Series firewalls.

NOTE: The AES-128-CCM encryption algorithm is not recommended for use.

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write Panorama administrator to push a specially crafted configuration to a PAN-OS node. This enables impersonation of a legitimate PAN-OS administrator who can perform restricted actions on the PAN-OS node after the execution of JavaScript in the legitimate PAN-OS administrator's browser.

An information exposure vulnerability in Palo Alto Networks PAN-OS software enables a local system administrator to unintentionally disclose secrets, passwords, and tokens of external systems. A read-only administrator who has access to the config log, can read secrets, passwords, and tokens to external systems.

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.

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.

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.

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.

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 blind XML External Entities (XXE) injection vulnerability in the Palo Alto Networks PAN-OS software enables an authenticated attacker to exfiltrate arbitrary files from firewalls to an attacker controlled server. This attack requires network access to the firewall management interface.

A server-side request forgery in PAN-OS software enables an authenticated attacker to use the administrative web interface as a proxy, which enables the attacker to view internal network resources not otherwise accessible.

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 null pointer dereference vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop a core system service on the firewall by sending a crafted packet through the data plane that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

A null pointer dereference vulnerability in the GlobalProtect gateway in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop the GlobalProtect service on the firewall by sending a specially crafted packet that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

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:
