Last revised: 05/29/2015

Summary

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)

Available Updates

PAN-OS 5.0.16; PAN-OS 6.0.8; PAN-OS 6.1.4

Workarounds and Mitigations
