Quick assessment

Affected
mariadb-corporation mariadb-connector-nodejs
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.

MariaDB Connector/Node.js 用于将基于 Node.js 开发的应用程序连接到 MariaDB 和 MySQL 数据库。在版本 3.2.0 至 3.2.5、3.3.4、3.4.7 以及 3.5.4 中，如果应用程序启用了 选项，则可能传入其键名会被展开为 SQL SET 子句的对象，而这些键名未经过 函数的处理。攻击者可以构造包含反引号（`）的恶意键名，从而闭合标识符的引用，并使键名的其余部分被解释为 SQL 代码。这可能导致应用程序意外更新未打算暴露的列，并以当前数据库用户的权限追加执行任意

Vulnerability Title
MariaDB Connector/Node.js: SQL injection through object keys in SET expansion (permitSetMultiParamEntries)
Source: CVE Program / CVE List V5
Vulnerability Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. From 3.2.0 until 3.2.5, 3.3.4, 3.4.7, and 3.5.4, applications that enable permitSetMultiParamEntries can pass objects whose keys are expanded into a SQL SET clause without being processed by escapeId. An attacker-controlled key containing a backtick can close the quoted identifier and cause the remainder of the key to be interpreted as SQL. This can update columns the application did not intend to expose and can append arbitrary SQL with the database user's privileges. The option is disabled by default, and serialized-object handling used when it is disabled is not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.
