#Windows Authentication Methods

**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.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L) but have no effect on integrity (I:N) or on availability (A:N). What does that mean for this vulnerability?** An attacker who successfully exploited the vulnerability could view some sensitive information (Confidentiality) but not all resources within the impacted component may be divulged to the attacker. The attacker cannot make changes to disclosed information (Integrity) or limit access to the resource (Availability).

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** The authentication feature could be bypassed as this vulnerability allows impersonation.

**According to the CVSS metrics, successful exploitation of this vulnerability does not impact confidentiality (C:N) but has major impact on integrity (I:H) and availability (A:H). What does that mean for this vulnerability?** An attacker who successfully exploits this vulnerability cannot access existing files (C:N) but can write or overwrite file contents (I:H), which potentially may cause the system to become unavailable (A:H).

**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 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.

**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 take additional actions prior to exploitation to prepare the target environment.

**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 take additional actions prior to exploitation to prepare the target environment.
