Windows Hyper-V Remote Code Execution Vulnerability

How would an attacker exploit this vulnerability? This vulnerability would require an authenticated attacker on a guest VM to send specially crafted file operation requests on the VM to hardware resources on the VM which could result in remote code execution on the host server.

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.

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, successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? An attacker who successfully exploited this vulnerability could potentially execute a cross-VM attack, thereby compromising multiple virtual machines and expanding the impact of the attack beyond the initially targeted VM.
