    monitor page alllows an unauthenticated attacker in the same

    Scripting attack. (CVE-2019-6697)

  - A Denial of Service vulnerability exists in the SSL VPN portal of
    FortiOS that allows an unauthenticated remote attacker to crash
    the SSL VPN service by sending a crafted POST request.
