FAQ

According to the CVSS metric, the attack vector is local (AV:L) while user interaction is required (UI:R). What does that mean for this vulnerability?

An attacker can trick a local user on a vulnerable system into mounting a specially crafted VHD that would then trigger the vulnerability.

Why could an attacker achieve remote code execution on affected versions of Window Server 2008, but only cause denial of service on systems running Window Server 2008 R2 or newer versions of Windows?

In Windows 7 and newer, an existing mechanism prevents an attacker from achieving remote code execution. They could only use this vulnerability to cause denial of service.
