FAQ

If I normally install GDR versions and have not installed the June Cumulative Update, am I affected by the vulnerability? Yes, customers who have installed Microsoft SQL Server 2022 for x64-based Systems (GDR) or Microsoft SQL Server 2019 for x64-based Systems (GDR) are vulnerable. Microsoft recommends updating to the latest cumulative update to be protected from this vulnerability. How could an attacker exploit this vulnerability? An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.
