**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** A user would need to join a malicious Microsoft Teams meeting set up by the attacker.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** A user would need to join a malicious Microsoft Teams meeting set up by the attacker.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited this vulnerability could gain administrator privileges.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. Additionally, an attacker could convince a local user to open a malicious file. The attacker would have to convince the user to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**Why is this AMD CVE included in the Security Update Guide?** The vulnerability assigned to this CVE is in certain processor models offered by AMD. The mitigation for this vulnerability requires a Windows update. This CVE is being documented in the Security Update Guide to announce that the latest builds of Windows enable the mitigation and provide protection against the vulnerability. Please see the following for more information: * AMD-SB-7005

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker would have to send the victim a malicious file that the victim would have to execute.

**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.

**How could an attacker exploit this vulnerability?** An authenticated attacker who is on the same intranet as the Exchange server can achieve remote code execution via a PowerShell remoting session.

**What type of information could be disclosed by this vulnerability?** This vulnerability makes it possible to listen to any group or user with a specially crafted group/username. By exploiting this vulnerability, the attacker can now receive messages for group(s) that they are unauthorized to view.
