Description

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.

Product Status

Versions	Affected	Unaffected
Cloud NGFW	None	All
PAN-OS 11.2	None	All
PAN-OS 11.1	< 11.1.5	>= 11.1.5
PAN-OS 11.0	< 11.0.6	>= 11.0.6
PAN-OS 10.2	< 10.2.11	>= 10.2.11
PAN-OS 10.1	None	All
Prisma Access	None	All

Required Configuration for Exposure

This issue impacts only firewalls on which you configured a GlobalProtect gateway. You can verify whether you configured GlobalProtect gateway by checking for entries in your firewall web interface (Network → GlobalProtect → Gateways).

Severity: MEDIUM, Suggested Urgency: MODERATE
