Elasticsearch ESA-2018-10

Medium Nessus Plugin ID 112045

Synopsis

The remote web server hosts a Java application that is affected by an
unauthorised information disclosure vulnerability.

Description

In 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.

Solution

All 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.
