CVE-2014-3120
Elasticsearch Remote Code Execution Vulnerability
What it is
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. NOTE: this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
CISA: Elasticsearch enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code.
What to do
Apply updates per vendor instructions.
