"The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 10.2.x, 11.1.x, 11.2.x,
12.1.x, or 12.2.x. It is, therefore, affected by a vulnerability.

    An improper input handling vulnerability in the GlobalProtect gateway of Palo Alto Networks PAN-OS
    software enables an authenticated user to establish a GlobalProtect session using the identity of another
    user.

    Cloud NGFW and Panorama 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.");
