Protect Yourself from a Microsoft SQL Server Vulnerability

CVSScvssV3_1: 8.8

Microsoft SQL Server is a popular database management system used by many organizations worldwide. Unfortunately, researchers recently discovered a remote code execution vulnerability in one of SQL Server’s components.

The vulnerability is in the Windows Data Access Components (WDAC) OLE DB provider for SQL Server. This is a library that allows applications to connect to and interact with SQL Server databases. A remote attacker could potentially exploit this vulnerability to execute arbitrary code on the targeted system with the same privileges as the SQL Server service.

So in summary, by sending specially crafted requests to the WDAC OLE DB provider, an attacker may be able to run any code they want on the server. This could allow them to install programs, view, change or delete data, or create new accounts with full access.

The good news is that Microsoft has released an update to patch this vulnerability. It is important that all SQL Server installations apply the update as soon as possible to close this security hole. Administrators should also ensure that only authorized users and applications can access the database server.

If you manage any SQL Server databases, be sure to install the latest updates right away. Also review your configuration to minimize exposure. Taking quick action can help protect you from this potential remote code execution vulnerability.
