CVE-2023-28228: Windows Spoofing Vulnerability

**How could an attacker successfully exploit this vulnerability?** An attacker could convince a user on the target device to open a maliciously crafted HTA file designed to appear as a legitimately signed WIM file (Windows Imaging Format).

CVE-2023-28227: Windows Bluetooth Driver Remote Code Execution Vulnerability

**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 gather information specific to the environment of the targeted component.

CVE-2023-28234: Windows Secure Channel Denial of Service Vulnerability

**Does this vulnerability affect all versions of TLS?** No. Only those devices running TLS 1.3 are affected. For more information on supported TLS implementations please visit: https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

CVE-2023-28231: DHCP Server Service Remote Code Execution Vulnerability

**How could an attacker exploit this vulnerability?** An authenticated attacker could leverage a specially crafted RPC call to the DHCP service to exploit this vulnerability.

CVE-2023-28229: Windows CNG Key Isolation Service Elevation of Privilege Vulnerability

**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.

CVE-2023-28220: Layer 2 Tunneling Protocol Remote Code Execution Vulnerability

**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.

CVE-2023-28219: Layer 2 Tunneling Protocol Remote Code Execution Vulnerability

**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.

CVE-2023-28226: Windows Enroll Engine Security Feature Bypass Vulnerability

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** The attacker must inject themselves into the logical network path between the target and the resource requested by the victim to read or modify network communications. This is called a man-in-the-middle (MITM) attack.
