Vulnerabilidad alta en MongoDB Connector for BI ODBC: desbordamiento de búfer por inyección SQL

Un atacante puede enviar consultas SQL malformadas a través del controlador ODBC de MongoDB Connector for BI, especificando nombres de cursor que exceden los límites internos del búfer. Esto provoca sobrescritura de memoria adyacente, potencialmente causando denial of service (DoS) o ejecución de código arbitrario en aplicaciones que integren este conector. Afecta directamente a plataformas de análisis y Business Intelligence que dependan de este driver en entornos LATAM.

Vulnerabilidad de memoria en MongoDB BI Connector ODBC Driver (CVE-2026-81533)

El controlador ODBC de MongoDB BI Connector presenta un fallo de seguridad de memoria (CVSS 7.1) cuando procesa sentencias SQL con secuencias de dígitos inusualmente largas en cláusulas LIMIT, afectando solo conexiones con la opción de prefetch habilitada. La vulnerabilidad se origina por copia insegura de datos a un búfer interno de tamaño fijo sin validación de límites. Empresas en LATAM que utilizan este driver para consultas analíticas en MongoDB deben revisar inmediatamente su configuración de prefetch y aplicar los parches disponibles del fabricante.
