Palo Alto Networks PAN-OS for Panorama < 9.0.15 / 9.1.12-h3 / 10.0.8-h8 Multiple RCE (Log4Shell)

critical Nessus Plugin ID 157876


The remote PAN-OS host is affected by multiple remote code execution vulnerabilities.


The version of Palo Alto Networks PAN-OS for Panorama running on the remote host is 9.0.x prior to 9.0.15, 9.1.x prior to 9.1.12-h3, or 10.0.x prior to 10.0.8-h8. It is, therefore, affected by two remote code execution vulnerabilities related to Log4Shell within the ElasticSearch component. These vulnerabilities allows a remote, unauthenticated attacker to execute arbitrary code on the affected host.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to PAN-OS 9.0.15, 9.1.12-h3, 10.0.8-h8, or later
