**How could an attacker exploit this vulnerability?** An authenticated attacker with normal privileges could send a modified XPS file to a shared printer, which can result in a remote code execution.
**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker would only be able to delete targeted files on a system. They would not gain privileges to view or modify file contents.
**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, privileges required is high (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker or targeted user to have specific elevated privileges. As is best practice, regular validation and audits of administrative groups should be conducted.
**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, privileges required is low (PR:L). What does that mean for this vulnerability?** The user must be authenticated to be able to exploit this 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 type of information could be disclosed by this vulnerability?** This vulnerability causes a verbose error message that could provide attacker with enough information to construct a malicious payload.
**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.
