             Summary: Kafka Connect REST endpoints reveal Password typed values
                 Key: KAFKA-5117
                 URL: https://issues.apache.org/jira/browse/KAFKA-5117
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 0.10.2.0
            Reporter: Thomas Holmes


A Kafka Connect connector can specify ConfigDef keys as type of Password. This type was added to prevent logging the values (instead "[hidden]" is logged).

This change does not apply to the values returned by executing a GET on {{connectors/\{connector-name\}}} and {{connectors/{connector-name}/config}}. This creates an easily accessible way for an attacker who has infiltrated your network to gain access to potential secrets that should not be available.

I have started on a code change that addresses this issue by parsing the config values through the ConfigDef for the connector and returning their output instead (which leads to the masking of Password typed configs as [hidden]).
