SynopsisThe remote web server hosts a Java application that is affected by an unauthorised information disclosure vulnerability.
DescriptionIn Elasticsearch versions 6.0.0-beta1 to 6.2.4 a disclosure flaw was found in the _snapshot API. When the access_key and security_key parameters are set using the _snapshot API they can be exposed as plain text by users able to query the _snapshot API.Although it is advised in the 6.X _snapshot API documentation to define the access_key and security_key parameters in the keystore, it is still possible to define them outside of the keystore using the API.
SolutionAll users of Elasticsearch should upgrade to version 6.3.0. This update will prevent the _snapshot API from returning the access_key and security_key parameters in plain text.
