Palo Alto Networks PAN-OS 8.1.x < 8.1.16 / 9.0.x < 9.0.10 / 9.1.x < 9.1.4 / 10.0.x < 10.0.1 DoS

medium Nessus Plugin ID 140527

Synopsis

The remote PAN-OS host is affected by a denial of service vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.16, 9.0.x prior to 9.0.10, 9.1.x prior to 9.1.4, or 10.0.x prior to 10.0.1. It is, therefore, affected by a denial of service (DoS) vulnerability.
An uncontrolled resource consumption vulnerability in Palo Alto Networks PAN-OS allows for a remote, unauthenticated user to upload temporary files through the management web interface that are not properly deleted after the request is finished. It is possible for an attacker to disrupt the availability of the management web interface by repeatedly uploading files until available disk space is exhausted.

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 8.1.16 / 9.0.10 / 9.1.4 / 10.0.1 or later
