Microsoft Office Remote Code Execution Vulnerability
FAQ: 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 running malicious files.
FAQ: 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.
The vulnerable endpoint is only available over the local VM interface as all external communication is blocked. This means an attacker needs to execute code from the local machine to exploit the vulnerability.
