title: PAN-OS: Improper Privilege Management Vulnerability in Panorama Software Leads to Availability Loss
description: An improper authorization vulnerability in Palo Alto Networks Panorama software enables an authenticated read-only administrator to upload files using the web interface and completely fill one of the disk partitions with those uploaded files, which prevents the ability to log into the web interface or to download PAN-OS, WildFire, and content images.
This issue affects only the web interface of the management plane; the dataplane is unaffected.
