#SQL Server

**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.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**There are GDR and/or CU (Cumulative Update) updates offered for my version of SQL Server. How do I know which update to use?** * First, determine your SQL Server version number. For more information on determining your SQL Server version number, see Microsoft Knowledge Base Article 321185 - How to determine the version, edition, and update level of SQL Server and its components. * Second, in the table below, locate your version number or the version range that your version number falls within. The corresponding update is the one you need to install. **Note** If your SQL Server version number is not represented in the table below, your SQL Server version is no longer supported. Please upgrade to the latest Service Pack or SQL Server product in order to apply this and future security updates. Update number Title Apply if current product version is… This security update also includes servicing releases up through… 5021522 Security update for SQL Server 2022 RTM+GDR (Feb 2023...

SQL Data Quality Services enables you to build a knowledge base and use it to perform a variety of critical data quality tasks. The vulnerability is only exploitable if this optional feature is enabled and running on an SQL instance. Additionally, the feature is not available in Azure SQL instances.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must convince the user to open a file on a malicious SQL server.
