Palo Alto Networks PAN-OS 10.2.x / 11.1.x / 11.2.x / 12.1.x Vulnerability

medium Nessus Plugin ID 325716

Synopsis

The remote PAN-OS host is affected by a vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 10.2.x, 11.1.x, 11.2.x, or 12.1.x. It is, therefore, affected by a vulnerability.

Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

Panorama is not impacted by these vulnerabilities.

Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

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

Solution

Upgrade to a fixed version
