"The version of Palo Alto Networks PAN-OS running on the remote host is
7.0.x prior to 7.0.8. It is, therefore, affected by the following
vulnerabilities :

  - A denial of service vulnerability exists in the API
    hosted on the management interface, specifically in the
    panUserLogin() function within panmodule.so, due to
    improper validation of user-supplied input to the
    'username' and 'password' parameters. An
    unauthenticated, remote attacker can exploit this, via a
    crafted request, to cause the process to terminate.
    (PAN-SA-2016-0008)

  - A cross-site scripting (XSS) vulnerability exists in the
    Application Command Center (ACC) due to improper
    sanitization of user-supplied input before returning it
    to users. An authenticated, remote attacker can exploit
    this, via a specially crafted request, to execute
    arbitrary script code in a user's browser session.
