Apache Druid 未授权访问漏洞分析及防护措施
在现代数据管理中,Apache Druid 作为一款高性能的开源时间序列数据库,因其出色的可扩展性和快速的数据处理能力而备受青睐。然而,最近披露的一项未授权访问漏洞引发了广泛关注。该漏洞影响了多个版本的 Apache Druid,使得攻击者能够绕过身份验证机制,从而未经授权地访问敏感数据。
受影响版本概述
根据最新的信息,以下版本的 Apache Druid 存在未授权访问漏洞:
- Apache Druid 0.24.0 至 0.24.2
- Apache Druid 0.25.0 至 0.25.2
- Apache Druid 0.26.0 至 0.26.1

漏洞详情与利用方式
This vulnerability is rooted in the GraphQL API of Apache Druid, where attackers can construct specially crafted GraphQL queries to bypass authentication mechanisms and gain unauthorized access to data within the cluster.
The exploitation process requires knowledge of the URL and port of the affected Druid cluster, allowing attackers to use a GraphQL client (like Apollo Client) to execute queries such as:
query { dataSource(name: "dataSourceName") { aggregations { sum(fieldName) } }}
This query can be executed without proper authentication, returning aggregated results from specified fields in designated data sources, potentially exposing sensitive information like financial records or user activity logs.
缓解措施建议
The recommended course of action for users operating on affected versions includes upgrading to one of the following secure releases:
- Druid 0.24.3
- Druid 0.25.3
- Druid 0.26.X (latest)
Additionally, it is advisable for users to implement further security measures such as:
- Limiting access to the Druid cluster exclusively for authorized personnel. < li >Utilizing firewalls to restrict access specifically targeting the GraphQL API. li >
- Monitoring logs diligently for any suspicious activities that may indicate attempts at unauthorized access. li > ul >
