#Windows Resilient File System (ReFS)

Improper access control in Windows FileSystemWatcher allows an authorized attacker to disclose information over a network.

**According to the CVSS metric, successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** In this case, a successful attack could be performed from a low privilege AppContainer. The attacker could elevate their privileges and execute code or access resources at a higher integrity level than that of the AppContainer execution environment.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of initialized or uninitialized memory in the process heap.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**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.
