FAUCET Score

CVE-2016-3281 is a memory corruption vulnerability affecting multiple versions of Microsoft Office, Word, Office Web Apps, and SharePoint Server. It allows remote attackers to execute arbitrary code through a crafted Office document. Rated with a CVSS score of 7.8 (High), this vulnerability requires user interaction (UI:R) and local access (AV:L) but can lead to complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H).
