"The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 8.1.x, 9.0.x, 9.1.x,
10.0.x, 10.2.x, or 11.0.x. It is, therefore, affected by a vulnerability.

    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.

Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
