PAN-OS: Stored Cross-Site Scripting (XSS) Vulnerability in the Web Interface

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface. Then, when viewed by a properly authenticated administrator, the JavaScript payload executes and disguises all associated actions as performed by that unsuspecting authenticated administrator.

Work around:
This issue requires the attacker to have authenticated access to the PAN-OS web interface. You can mitigate the impact of this issue by following the Best Practices for Securing Administrative Access in the PAN-OS technical documentation at https://docs.paloaltonetworks.com/best-practices.
