QID 731368: Palo Alto Networks (PAN-OS) Firewall Denial of Service (DoS) via Malformed NTLM Packets Vulnerability (PAN-198992)

PAN OS is the software that runs all Palo Alto Networks next-generation firewalls.

A vulnerability in Palo Alto Networks PAN-OS software enables a remote attacker to reboot PAN-OS firewalls when receiving Windows New Technology LAN Manager (NTLM) packets from Windows servers. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online.

Affected Versions:
PAN-OS 10.0 versions earlier than PAN-OS 10.0.12
PAN-OS 9.1 versions earlier than PAN-OS 9.1.15-h1
PAN-OS 9.0 versions earlier than PAN-OS 9.0.17
PAN-OS 8.1 versions earlier than PAN-OS 8.1.24


QID Detection Logic (Authenticated):

This QID looks for the vulnerable version of PAN-OS

NOTE:This issue affects only PAN-OS configurations with NTLM authentication enabled. You should verify whether NTLM authentication is enabled by checking your firewall web interface (Device > User Identification > User Mapping > Palo Alto Networks User-ID Agent Setup > NTLM).
