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 11.1.x prior to 11.1.16-h5, 11.2.x prior to 11.2.16-h2, 12.1.x prior to 12.1.10-h4, or 12.2.x prior to 12.2.4-h2. It is, therefore, affected by a vulnerability.

An authorization bypass vulnerability in the GlobalProtect gateway of Palo Alto Networks PAN-OS software enables an authenticated attacker with valid GlobalProtect credentials to bypass IP address restrictions and circumvent network access controls that rely on source IP filtering.

Cloud NGFW is not affected by this vulnerability.


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 PAN-OS 11.1.16-h5 / 11.2.16-h2 / 12.1.10-h4 / 12.2.4-h2 or later
