**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, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to successfully execute a blind XXE attack.
**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.
**How could an attacker exploit this vulnerability?** In most situations, an unauthenticated attacker could send a specially crafted packet to a targeted server utilizing the Server Name Indication (SNI) over HTTP Protocol Stack (http.sys) to process packets, causing a denial of service (DOS).

**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.
**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.
**What type of privileges could an attacker gain through this vulnerability?** A domain user could use this vulnerability to elevate privileges to SYSTEM assigned integrity level.
**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that a user trigger the payload in the application.
