Threat Report – Palo Alto Patch – April 2024

Threat Reports are reports created by Smarttech247 based on high and critical severity vulnerabilities that may have a high potential to be exploited in the wild i.e. vulnerabilities that are present in most used products by companies and do not have an auto-update option or they are usually not automatically updated in case that could lead to some service disruption


A command injection vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software for specific PAN-OS versions and distinct feature configurations may enable an unauthenticated attacker to execute arbitrary code with root privileges on the firewall.

Cloud NGFW, Panorama appliances, and Prisma Access are not impacted by this vulnerability.

Users should continue to monitor this security advisory for the latest updates and product guidance.

Palo Alto Networks has released fixes for a zero-day vulnerability affecting its GlobalProtect VPN product that is being targeted following its disclosure last week. Hotfixes for the vulnerability – labelled CVE-2024-3400 – were published on Sunday.

Required Configuration for Exposure:

This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, and PAN-OS 11.1 firewalls configured with GlobalProtect gateway or GlobalProtect portal (or both). Device telemetry does not need to be enabled for PAN-OS firewalls to be exposed to attacks related to this vulnerability.

Users can verify whether you have a GlobalProtect gateway or GlobalProtect portal configured by checking for entries in their firewall web interface (Network > GlobalProtect > Gateways or Network > GlobalProtect > Portals).


We strongly advise users to immediately upgrade to a fixed version of PAN-OS to protect their devices even when workarounds and mitigations have been applied.

This issue is fixed in hotfix releases of PAN-OS 10.2.9-h1, PAN-OS 11.0.4-h1, PAN-OS 11.1.2-h3, and in all later PAN-OS versions. Hotfixes for other commonly deployed maintenance releases will also be made available to address this issue. Please see details below for ETAs regarding the upcoming hotfixes.PAN-OS 10.2:

Workarounds and Mitigations:

Recommended Mitigation: Users with a Threat Prevention subscription can block attacks for this vulnerability using Threat IDs 95187, 95189, and 95191 (available in Applications and Threats content version 8836-8695 and later).

To apply the Threat IDs, users must ensure that vulnerability protection has been applied to their GlobalProtect interface to prevent exploitation of this issue on their device. Please see for more information.

In earlier versions of this advisory, disabling device telemetry was listed as a secondary mitigation action. Disabling device telemetry is no longer an effective mitigation. Device telemetry does not need to be enabled for PAN-OS firewalls to be exposed to attacks related to this vulnerability.

Note: The vendor advisory originally indicated that device telemetry needed to be enabled in addition to GlobalProtect Portal or Gateway; as of April 16, the advisory notes that “Device telemetry does not need to be enabled for PAN-OS firewalls to be exposed to attacks related to this vulnerability.” Disabling device telemetry is also no longer considered an effective mitigation.
