CVE-2014-3120: Elasticsearch Improper Access Control vulnerability
(updated )
The default configuration in Elasticsearch before 1.4.0.Beta1 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. NOTE: this only violates the vendor’s intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
