CVE-2024-26214Network attack vector

Remote code execution via malicious SQL server replies

Published Apr 9, 2024 · Updated May 3, 2025

Heap-based buffer overflow in the Microsoft WDAC SQL Server ODBC Driver allows remote attackers to execute code via a malicious SQL server. Specially crafted server replies overrun a heap buffer in the connection driver, although Microsoft has not disclosed the affected parser or copy operation. Exploitation requires an authenticated user to be persuaded to connect with a SQL client, and resulting code runs in that client application's user context.
