Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
MongoDB BI Connector是美国MongoDB公司的一个连接商业智能工具与数据库的桥梁。 MongoDB BI Connector 2.1.0版本至2.14.31之前版本存在SQL注入漏洞，该漏洞源于对集合JSON模式验证器描述文本中的反斜杠字符转义不完整，可能导致具有修改模式验证器权限的用户将额外SQL文本嵌入到SHOW CREATE语句返回的DDL注释中，若后续重放执行，额外文本将以会话权限执行。

Vulnerability Title
MongoDB Connector for BI Incomplete Escaping of Stored Metadata in Generated SHOW CREATE Output
Source: CVE Program / CVE List V5
Vulnerability Description
In MongoDB Connector for BI, the description text of a collection's JSON schema validator is incorporated into the comment text of the DDL returned by SHOW CREATE statements without complete escaping of backslash characters. A user with permission to modify a collection's schema validator, in deployments configured to build their SQL schema from those validators, can cause additional SQL text to be embedded in that generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.
