Why does the CVE title indicate that this is a remote code execution?</strong></p>\n<p>The word <strong>Remote</strong> 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.</p>\n","ordinal":10000},{"articleType":"FAQ","description":"<p><strong>According to the CVSS metric, privileges required is low (PR:L).
