**According to the CVSS metrics, successful exploitation of this vulnerability could lead to minor loss of confidentiality (C:L), integrity (I:L) and availability (A:L). What does that mean for this vulnerability?** While we cannot rule out the impact to Confidentiality, Integrity, and Availability, the ability to exploit this vulnerability by itself is limited. An attacker would need to combine this with other vulnerabilities to perform an attack.

**What actions do customers need to take to protect themselves from this vulnerability?** Customers who have disabled Automatic Extension Upgrades or would like to upgrade an extension immediately must manually update their Azure Monitor Agent to the latest version. For more information on how to perform a manual update, see Manage Azure Monitor Agent.

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

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment of the targeted component.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**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, user interaction is required (UI:R). What interaction would the user have to do?** Successful exploitation of this vulnerability requires a user to open a malicious email with an affected version of Microsoft Outlook and then perform specific actions to trigger the vulnerability.

**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.
