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.
  impact: |
    Allows remote attackers to execute arbitrary code on the affected system
  remediation: |
    Upgrade to a patched version of ElasticSearch
