**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors might be helpful in your situation: * Systems are not affected if IPv6 is disabled on the target machine.

**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 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, user interaction is required (UI:R). What interaction would the user have to do?** The attacker must convince a user to call Windows App Installer with a specially crafted malicious winget file.

**Windows 11, version 24H2 is not generally available yet. Why are there updates for this version of Windows listed in the Security Updates table?** The new Copilot+ devices that are now publicly available come with Windows 11, version 24H2 installed. Customers with these devices need to know about any vulnerabilities that affect their machine and to install the updates if they are not receiving automatic updates. Note that the general availability date for Windows 11, version 24H2 is scheduled for later this year.

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

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

**How do I protect myself from this vulnerability?** The vulnerability pertains to a previous installer version which has been superseded by the new WinRE installer. Since the vulnerability is only exploitable at the install time, users need to take no action to be protected from this vulnerability. See the linked Article in the Security Updates table about the update for your particular Windows version.

**According to the CVSS metric, the attack vector is physical (AV:P). What does that mean for this vulnerability?** To exploit this vulnerability, an attacker needs physical access to the victim's machine.
