The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.16 or 9.0.x prior to 9.0.9. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in the management web interface. An unauthenticated, remote attacker can exploit this, by convincing an administrator with an active authenticated session on the firewall management interface to click on a crafted link in order to execute arbitrary JavaScript code in the administrator’s browser and perform administrative actions.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
