Description
An external control of filename vulnerability in the command processing of

PAN-OS 8.1 versions before 8.1.14;
PAN-OS 9.0 versions before 9.0.7;
PAN-OS 9.1 versions before 9.1.1.

Solution
This issue is fixed in PAN-OS 8.1.14, PAN-OS 9.0.7, PAN-OS 9.1.1, 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.
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.
