"The remote PAN-OS host is affected by a vulnerability");

"The version of Palo Alto Networks PAN-OS running on the remote host is 10.2.x prior to 10.2.17, 11.1.x prior to 11.1.12,
or 11.2.x prior to 11.2.8. It is, therefore, affected by a vulnerability.

    An information disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated
    administrator to view session tokens of users authenticated to the firewall web UI. This may allow
    impersonation of users whose session tokens are leaked. 

    The security risk posed by this issue is significantly minimized when CLI access is restricted to a
    limited group of administrators.

    Cloud NGFW and Prisma Access are not affected by this vulnerability.

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.");
