"The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 9.1.x, 10.1.x, 10.2.x,
11.0.x, or 11.1.x. It is, therefore, affected by a vulnerability.

    This vulnerability allows an attacker performing a meddler-in-the-middle attack between Palo Alto Networks
    PAN-OS firewall and a RADIUS server to bypass authentication and escalate privileges to superuser' when
    RADIUS authentication is in use and either CHAP or PAP is selected in the RADIUS server profile.

    CHAP and PAP are protocols with no Transport Layer Security (TLS), and hence vulnerable to meddler-in-the-
    middle attacks. Neither protocol should be used unless they are encapsulated by an encrypted tunnel. If
    they are in use, but are encapsulated within a TLS tunnel, they are not vulnerable to this attack.

    For additional information regarding this vulnerability, please see https://blastradius.fail.

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.");
