Code execution via malformed SQL server response
Published Jun 16, 2023 · Updated Feb 28, 2025
Heap-based buffer overflow in Microsoft ODBC Driver for SQL Server allows attackers to execute code through a malicious server response. The driver writes server-supplied data beyond a heap buffer, but Microsoft has not identified the affected parser or field. Exploitation requires a user or application to connect to an attacker-controlled SQL Server; successful execution runs in the client process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
