Description

An XML parsing vulnerability exists in PAN-OS allowing a malicious user within PAN-OS to inject malicious XML data into the web-based device management front-end allowing the user to retrieve arbitrary content from the device. The user must be an authenticated user issuing the request. (Ref #71273)

This issue affects the management interface of the device, where an authenticated administrator injects malicious XML data into the web UI interface.

This issue affects PAN-OS 5.0.15 and earlier; PAN-OS 6.0.7 and earlier; PAN-OS 6.1.3 and earlier
