尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
Apache Hive 4.2.1 之前版本（所有平台）的 Hive Metastore 中，当启用直接 SQL（默认启用）时，存在 SQL 注入漏洞，位于通过直接 SQL 解析分区名称（partition-name resolution）的过程中。经过身份认证并有权访问 Hive Metastore API 的攻击者，可以通过在 Metastore RPC 请求中构造恶意分区名称，读取、修改或影响非预期的分区元数据（包括统计信息更新、截断目标以及文件元数据缓存操作）。建议用户升级至 4.2.1 版本以修复此问题。

Vulnerability Title
Apache Hive: SQL Injection vulnerability in HiveMetaStore partition-name direct-SQL paths
来源: CVE Program / CVE List V5
Vulnerability Description
SQL injection in Hive Metastore direct SQL partition-name resolution in Apache Hive before 4.2.1 on all platforms allows authenticated users with access to Hive Metastore APIs to read, modify, or affect unintended partition metadata (including statistics updates, truncation targets, and file-metadata cache operations) via crafted partition names in metastore RPC requests when direct SQL is enabled (the default). Users are recommended to upgrade to version 4.2.1, which fixes this issue.
Details about the issue:
Several Hive Metastore RPCs resolve partitions by full partition name (PART_NAME) through direct-SQL helpers. In those paths, client-supplied partition names are embedded into SQL using string concatenation (DirectSqlUpdatePart.quoteString() → '...') instead of bind parameters. A partition name containing a single quote (and crafted SQL) can alter the generated WHERE clause so that lookups intended for one partition match additional rows. That can affect reads, stats updates, truncate targets, metadata-cache targets, and related operations when metastore.try.direct.sql is enabled (default: true). An authenticated or network-trusted caller with the ability to invoke Hive Metastore partition-name APIs against a target table (directly or via Hive/other clients), when direct SQL is enabled can perform this attack. Also, the impact is mainly within table & partition targeting (read/update/truncate/drop/cache the wrong partitions in a table they can reference), not arbitrary cross-database access via this bug alone.
