Description

In MongoDB Connector for BI, MongoDB object names such as collection, field, and index names are placed into the quoted identifiers of the DDL text returned by SHOW CREATE statements without escaping the identifier delimiter. A user with permission to write to a sampled MongoDB collection can choose a name that closes the quoted identifier early, so that additional SQL text becomes part of the 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.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
