CVE-2014-3120

8.1 · HIGH Actively Exploited

Published Jul 28, 2014 elastic CWE-284 EPSS 88.56% (100th pctl) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N

Overview

CVE-2014-3120 is a high-severity vulnerability affecting elastic elasticsearch. It was published on July 28, 2014 and has a CVSS 3.1 base score of 8.1 (HIGH). This vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild.

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from elastic. Update elasticsearch to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
