CVE-2014-3120
Elasticsearch Remote Code Execution Vulnerability
- High 8.1
- Exploited: added to CISA KEV 25 Mar 2022
- A public exploit reference is listed
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. NOTE: this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
