Received Received - Intake

MongoDB BI Connector ODBC Driver Memory Corruption

Publication date: 2026-08-12

Last updated on: 2026-08-12

Assigner: MongoDB, Inc.

Description

A missing bounds check when parsing stored procedure parameter metadata in the MongoDB BI Connector ODBC Driver can result in an out-of-bounds write in the client application process. Triggering this issue requires control over the server the driver connects to, or the ability to respond in its place, in order to return malformed metadata. The resulting memory corruption may cause the client application to terminate abnormally or, under certain conditions, execute unintended code.

Attack-Flow Graph

Executive Summary

This vulnerability involves a missing bounds check in the MongoDB BI Connector ODBC Driver when parsing stored procedure parameter metadata. This can lead to an out-of-bounds write in the client application process. An attacker needs control over the server or the ability to respond in its place to return malformed metadata. The issue may cause abnormal termination of the client application or, under certain conditions, allow unintended code execution.

Detection Guidance

Detection requires monitoring for abnormal client application behavior or crashes when connecting to MongoDB servers. Check logs for out-of-bounds write errors or memory corruption in the MongoDB BI Connector ODBC Driver process. Ensure the driver version is up to date and inspect network traffic for malformed metadata responses from servers.

Impact Analysis

If exploited, this vulnerability could allow an attacker to crash the client application or execute arbitrary code on the system running the MongoDB BI Connector ODBC Driver. This could lead to data breaches, unauthorized access, or disruption of services relying on the driver.

Compliance Impact

This vulnerability could lead to unauthorized data access or disclosure, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Organizations using the affected driver may face legal penalties, reputational damage, and increased scrutiny from regulators.

Mitigation Strategies

Update the MongoDB BI Connector ODBC Driver to the latest version that includes bounds checking for stored procedure parameter metadata. Restrict network access to MongoDB servers to trusted sources only. Monitor client applications for crashes or unusual behavior after updates.
