CVE-2022-41048Network attack vector

Remote code execution via malicious SQL server packet

Published Nov 9, 2022 · Updated Aug 10, 2026

Remote code execution in Microsoft ODBC Driver on affected Windows releases allows remote attackers to run code via a malicious SQL server. Microsoft discloses only that a malicious network packet returned by the server reaches the ODBC client; the exact parsing defect is not public. Exploitation requires an authenticated user to be tricked into initiating the ODBC connection, after which code executes on that client.
