CVE-2018-3825

Quick assessment

Affected
Elastic Elastic Cloud Enterprise (ECE)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elastic Cloud Enterprise（ECE）是荷兰Elasticsearch公司的一套用于管理、监控和配置Elasticsearch、Kibana和X-Pack的软件包。 ECE 1.1.4版本中存在安全漏洞，该漏洞源于在授权ZooKeeper访问Elasticsearch集群的过程中程序使用了默认的master加密密钥，除非被明确地覆盖，否则该master密钥在所有的ECE部署范围内都是可预测的。攻击者可通过获取其他租户的集群ID并通过直接连接ZooKeeper利用该漏洞访问租户的配置信息

Source: CVE Program / CVE List V5
Vulnerability Description
In Elastic Cloud Enterprise (ECE) versions prior to 1.1.4 a default master encryption key is used in the process of granting ZooKeeper access to Elasticsearch clusters. Unless explicitly overwritten, this master key is predictable across all ECE deployments. If an attacker can connect to ZooKeeper directly they would be able to access configuration information of other tenants if their cluster ID is known.
