Synopsis

The remote web server hosts a Java application that is affected by multiple vulnerabilities.

Description

An error was found in the permission model used by X-Pack alerting whereby users mapped to certain built-in roles could create a watch that results in that user gaining elevated privileges.

Solution

Deployments of the Elastic Stack that utilize X-Pack alerting should be upgraded to version 5.6.1 to fix the privilege escalation issue.Users mapped to the built-in watcher_admin or machine_learning_admin roles, or any other role to which the manage_ml or manage_watcher cluster privilege has been assigned, should be reviewed and granted only to personnel with appropriate trust levels to read and write all indices.
