A cleartext storage of sensitive information vulnerability in FortiOS command line interface in versions 6.2.4 and earlier and FortiProxy 2.0.0, 1.2.9 and earlier may allow an authenticated attacker to obtain sensitive information such as users passwords by connecting to FortiGate CLI and executing the "diag sys ha checksum show" command.
An insufficient logging vulnerability in FortiGate before 6.4.1 may allow the traffic from an unauthenticated attacker to Fortinet owned IP addresses to go unnoticed.
