Elasticsearch ESA-2017-15

Low Nessus Plugin ID 112041

Synopsis

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

Description

An error was found in the X-Pack Security TLS trust manager for versions 5.0.0 to 5.5.1. If reloading the trust material fails the trust manager will be replaced with an instance that trusts all certificates. This could allow any node using any certificate to join a cluster. The proper behavior in this instance is for the TLS trust manager to deny all certificates.

Solution

X-Pack Security users should upgrade to version 5.5.2. Please note this attack cannot be triggered remotely. The most likely scenario would be local system corruption. Even though crossing a trust boundary cannot be forced by an attacker, we consider a security feature failing in this manner to be a flaw.
