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;
|9.0||< 9.0.7||>= 9.0.7|
|8.1||< 8.1.14||>= 8.1.14|
CVSSv3.1 Base Score: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
This issue is fixed in PAN-OS 8.1.14, PAN-OS 9.0.7, PAN-OS 9.1.0 and all later PAN-OS versions.
PAN-OS 8.0 is now end-of-life as of October 31, 2019, and is no longer covered by our Product Security Assurance policies.
PAN-OS 7.1 is on extended support until June 30, 2020, and is only being considered for critical security vulnerability fixes.
This issues affects the management interface of PAN-OS and is strongly mitigated by following best practices for securing the PAN-OS management interface.
