CVE-2022-34696

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.

According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?

Successful exploitation of this vulnerability requires an attacker to win a race condition.

According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?

Successful exploitation of this vulnerability could allow a Hyper-V guest to affect the functionality of the Hyper-V host.

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

An authenticated attacker who successfully exploited a race condition from a Hyper-V guest could attempt to trigger malicious code in the context of that user to attempt an arbitrary or remote code execution on the Hyper-V host.
