**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker to be able to send a malicious update package to the Defender for IoT sensor over the network. To do this, the attacker would first need to authenticate themselves and gain the necessary permissions to initiate the update process.

**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker to be an administrator of the web application. As is best practice, regular validation and audits of administrative groups should be conducted.

**According to the CVSS metric, the attack vector is Adjacent (AV:A), the attack complexity is high (AC:H) and the privileges required is high (PR:H). What does this mean for this vulnerability?** An authenticated attacker would need to have access to a proxy server created in the same or in an accessible network of the Appliance.

**I am running SQL Server on my system. What action do I need to take?** Update your relevant version of SQL Server. Any applicable driver fixes are included in those updates. **I am running my own application on my system. What action do I need to take?** Update your application to use Microsoft OLE DB Driver 18 or 19. Update the drivers to the versions listed on this page, which provide protection against this vulnerability. **I am running an application from a software vendor on my system. What action do I need to take?** Consult with your application vendor if it is compatible with Microsoft OLE DB Driver 18 or 19. Update the drivers to the versions listed in this page, which provide protection against this vulnerability **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 Micr...

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Any authenticated user could trigger this vulnerability. It does not require admin or other elevated privileges.

**How could an attacker exploit this vulnerability?** For successful exploitation, a malicious certificate needs to be imported on an affected system. An attacker could upload a certificate to a service that processes or imports certificates, or an attacker could convince an authenticated user to import a certificate on their system.

**How could an attacker exploit this vulnerability?** An attacker could exploit a DFS namespace (non-default) out-of-bound write vulnerability that results in heap corruption, which could then be used to perform arbitrary code execution on the server's dfssvc.exe process which runs as SYSTEM user.

**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.

**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. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
