#Security Vulnerability

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by sending the user a malicious link or a malicious image via Instant Message and then convincing the user to click the link or image.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An authenticated attacker who successfully exploited this vulnerability could prevent Microsoft Defender from starting.

**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, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.
