Summary

An information exposure vulnerability exists in Palo Alto Networks Panorama software that discloses the token for the Panorama web interface administrator's session to a managed device when the Panorama administrator performs a context switch into that device. This vulnerability allows an attacker to gain privileged access to the Panorama web interface. An attacker requires some knowledge of managed firewalls to exploit this issue. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.17; PAN-OS 9.0 versions earlier than PAN-OS 9.0.11; PAN-OS 9.1 versions earlier than PAN-OS 9.1.5.

Workarounds

This issue can be completely mitigated by enabling custom certificate authentication between Panorama and managed firewalls. See https://docs.paloaltonetworks.com/panorama/10-0/panorama-admin/set-up-panorama/set-up-authentication-using-custom-certificates.html This issue impacts the management web interface of appliances running PAN-OS software and is strongly mitigated by following best practices for securing the interface. Please review the Best Practices for Securing Administrative Access in the PAN-OS technical documentation, available at: https://docs.paloaltonetworks.com/best-practices
