"The version of Fortinet FortiAnalyzer running on the remote host is
5.0.x prior to 5.0.8. It is, therefore, potentially affected by an
information disclosure vulnerability due to passwords being printed in
plaintext by the 'Alert email debug' feature. This allows a local
attacker to view the passwords in the log when the 'Alert email debug'
feature is enabled.

Note that Nessus has not tested for this issue or the host
configuration but has instead relied only on the application's
self-reported version number.");
