MongoDB Connector for BI SQL Injection via Object Names

Assigner: MongoDB, Inc.

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.

Exploitability

CWE
CWE Icon
KEV
KEV Icon
CWE ID Description
CWE-89 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.

Executive Summary

This vulnerability exists in MongoDB Connector for BI where object names like collections or fields are inserted into SQL DDL statements without proper escaping. An attacker with write access can craft a name that manipulates the SQL statement, allowing additional SQL commands to be executed when the statement is replayed by an operator or tool.

Impact Analysis

If exploited, this flaw could allow unauthorized SQL command execution with the privileges of the session running the replayed statement. This may lead to data theft, manipulation, or system compromise depending on the SQL server's permissions.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating confidentiality and integrity requirements in GDPR and HIPAA. Organizations using MongoDB Connector for BI may face compliance violations if exploited.

Mitigation Strategies

Update MongoDB Connector for BI to the latest patched version immediately to prevent exploitation via crafted object names. Review and restrict write permissions on MongoDB collections to trusted users only to limit potential attack vectors.
