Palo Alto Networks 7.1.x < 7.1.22 / 8.0.x < 8.0.15 / 8.1.x < 8.1.6 Cross-Site Scripting Vulnerability (PAN-SA-2019-0001)

medium Nessus Plugin ID 122757


The remote host is affected by cross-site scripting (XSS) vulnerability that exists in the PAN-OS external dynamic lists.


The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 7.1.22 or 8.0.x prior to 8.0.15 or 8.1.x prior to 8.1.6. It is, therefore, affected by a cross-site scripting (XSS) vulnerability that exists in the PAN-OS external dynamic lists due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.


Upgrade to Palo Alto Networks PAN-OS version 7.1.22 / 8.0.15 / 8.1.6 or later.
