According to its self-reported version number, the remote host is running a version of FortiOS prior to 6.2.5. It, therefore, is vulnerable to information disclosure from data stored in clear text that can be accessed via specific commands run on FortiOS’ CLI. An authenticated, remote attacker could obtain sensative information up to and including user passwords by running a specific diagnostic command.
