What privileges could be gained by an attacker who successfully exploited the vulnerability?

An attacker who successfully exploited this vulnerability could gain administrator privileges.

According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?

Successful exploitation of this vulnerability requires an attacker to have access to the location where the target file will be run. They would then need to plant a specific file that would be used as part of the exploitation.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?

Successful exploitation requires the victim to install an affected version of the product which would trigger the vulnerability.

Is the Preview Pane an attack vector for this vulnerability?

No, the Preview Pane is not an attack vector.

How could an attacker exploit this vulnerability?

An unauthenticated attacker who successfully exploited this vulnerability could gain code execution through convincing a user to open a malicious document at which point the attacker could execute arbitrary code in the context of the user.

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, user interaction is required (UI:R). What interaction would the user have to do?

A user needs to be tricked into opening malicious files.

According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?

To successfully exploit this vulnerability, an attacker or the targeted user would need to achieve a high level of control over a machine, as the attack requires access to processes typically restricted from average users.

Essentially, the exploitation necessitates elevated privileges on the compromised machine due to the requirement of manipulating processes beyond the reach of standard user permissions.
