Palo Alto Networks Security Advisories / CVE-2020-2009
CVE-2020-2009 PAN-OS: Panorama SD WAN arbitrary file creation
Severity 7.2 . HIGH
Attack Vector NETWORK
Attack Complexity LOW
Privileges Required HIGH
User Interaction NONE
Confidentiality Impact HIGH
Integrity Impact HIGH
Availability Impact HIGH
An external control of filename vulnerability in the SD WAN component of Palo
Alto Networks PAN-OS Panorama allows an authenticated administrator to send a
request that results in the creation and write of an arbitrary file on all
firewalls managed by the Panorama. In some cases this results in arbitrary code
execution with root permissions.
This issue affects:
All versions of PAN-OS 7.1;
PAN-OS 8.1 versions earlier than 8.1.14;
PAN-OS 9.0 versions earlier than 9.0.7.
Versions Affected Unaffected
9.0 < 9.0.7 >= 9.0.7
8.1 < 8.1.14 >= 8.1.14
CVSSv3.1 Base Score: 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)
This issue is fixed in PAN-OS 8.1.14, PAN-OS 9.0.7, and all later PAN-OS
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.
Workarounds and Mitigations
This issue affects the management interface of PAN-OS and is strongly mitigated
by following best practices for securing the PAN-OS management interface.
Please review the Best Practices for Securing Administrative Access in the
PAN-OS technical documentation, available at: https://docs.paloaltonetworks.com
This issue was found by Nicholas Newsom and Jin Chen of Palo Alto Networks
during internal security review.
