CVE-2014-3120

Description

It was discovered that the default configuration of Elasticsearch enabled dynamic scripting, allowing a remote attacker to execute arbitrary MVEL expressions and Java code via the source parameter passed to _search.

Statement

On Subscription Asset Manager (SAM) 1, the elasticsearch service is only bound to the loopback interface by default. To exploit this issue on a SAM 1 system, an attacker must have local access to the system. On Red Hat JBoss Fuse and Red Hat JBoss A-MQ, the elasticsearch service is only started if the insight-elasticsearch feature is installed. This feature is not installed by default.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
