Elasticsearch ESA-2018-19

medium Nessus Plugin ID 121249

Synopsis

The remote web server hosts a Java application that is vulnerable.

Description

Elasticsearch Security versions 6.5.0 and 6.5.1 contain an XXE flaw in Machine Learnings find_file_structure API. If a policy allowing external network access has been added to Elasticsearchs Java Security Manager then an attacker could send a specially crafted request capable of leaking content of local files on the Elasticsearch node. This could allow a user to access information that they should not have access to.Please note: by default Elasticsearch has the Java Security Manager enabled with policies which will cause this attack to fail.

Solution

Affected users should upgrade to Elasticsearch version 6.5.2.
