**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.

**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.

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

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

**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 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.

**How could an attacker exploit the vulnerability?** To exploit this vulnerability, an attacker would need to send a specially crafted malicious MSMQ packet to a MSMQ server. This could result in remote code execution on the server side.

**Is the Preview Pane an attack vector for this vulnerability?** Yes, the Preview Pane is an attack vector.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited the vulnerability could elevate privileges and read any file on the file system with SYSTEM access permissions.
