**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 prepare the target environment to improve exploit reliability.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.

**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.

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

**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 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, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.

**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?** The attacker would gain the rights of the user that is running the affected application.
