Visible password at sensu-client logs after restart

[pdebashis]

Configuring single rabbitmq, sensu is able to redact the password in client logs after restart.
But when configuring multiple rabbitmqs, plain text password is visible.

Logs for single rabbitmq config :

{
   "timestamp":"2016-04-08T16:41:35.699673-0700",
   "level":"warn",
   "message":"config file applied changes",
   "file":"/etc/sensu/conf.d/rabbitmq.json",
   "changes":{
      "rabbitmq":[
         null,
         {
            "host":"1.1.1.1",
            "port":"5671",
            "user":"sensu",
            "password":"REDACTED"
         }
      ]
   }
}

Logs for multiple rabbitmq config :

{
   "timestamp":"2016-04-08T16:41:35.699673-0700",
   "level":"warn",
   "message":"config file applied changes",
   "file":"/etc/sensu/conf.d/rabbitmq.json",
   "changes":{
      "rabbitmq":[
         null,
         [
            {
               "host":"1.1.1.1",
               "port":"5671",
               "user":"sensu",
               "password":"abc123"
            },
            {
               "host":"1.1.1.2",
               "port":"5671",
               "user":"sensu",
               "password":"abc123"
            }
         ]
      ]
   }
}

This issue seems to occur because multilpe rabbitmq config is stored in a nested array format. Sensu is not able to look up the password keyword inside the hash, inside the array and hence, not able to redact the password in logs.

This is sensu-settings issue. We need to apply redact_sensitive on this line: https://github.com/sensu/sensu-settings/blob/master/lib/sensu/settings/loader.rb#L169

Thank you for the reply.

As per the analysis, redact_sensitive method is taken care during printing. Please note that the issue occurs only for multiple rabbitmq configuration.

I would like to request a CVE to be assigned for the issue.

Thank you for reporting this issue. A fix has been merged to master and we are working on releasing Sensu 1.2.1 which will contain the fix.
