Description
An improper input validation vulnerability in the configuration daemon of Palo
Alto Networks PAN-OS Panorama allows for a remote unauthenticated user to send
a specifically crafted registration request to the device that causes the
configuration service to crash. Repeated attempts to send this request result
in denial of service to all PAN-OS Panorama services by restarting the device
and putting it into maintenance mode.
This issue affects:
All versions of PAN-OS 7.1 and 8.0;
PAN-OS 8.1 versions earlier than 8.1.14;
PAN-OS 9.0 versions earlier than 9.0.7;

Solution
