"The version of Palo Alto Networks PAN-OS running on the remote host
is prior to 6.1, 7.x prior to 7.1, 8.1.x prior to 8.1.4. It is,
therefore, affected by a cross-site scripting (XSS) vulnerability that
exists in PAN-OS GlobalProtect portal login page due to improper
validation of user-supplied input before returning it to users. An
unauthenticated, remote attacker can exploit this, by convincing a
user to click a specially crafted URL, to execute arbitrary script
code in a user's browser session. (CVE-2018-10141)");
