CVE-2024-30064: 
vulnerability analysis and mitigation

Windows Kernel Elevation of Privilege Vulnerability (CVE-2024-30064) is a high-severity security flaw discovered in the Windows Distributed File System (DFS). The vulnerability was disclosed on June 11, 2024, and affects various versions of Microsoft Windows Server 2022. Microsoft has assigned it a CVSS v3.1 base score of 8.8 (HIGH) (Microsoft Advisory).

The vulnerability is classified as an Integer Overflow or Wraparound (CWE-190) issue. It has been assigned a CVSS vector of CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, indicating that it requires local access, low attack complexity, and low privileges to exploit, but can result in high impacts to confidentiality, integrity, and availability (NVD).

Successful exploitation of this vulnerability could allow an attacker to gain elevated privileges through a vulnerable DFS client, enabling them to locally execute arbitrary code in the kernel. This could potentially lead to complete system compromise with SYSTEM-level privileges (Talos).

The vulnerability requires the attacker to be locally authenticated and run a specially crafted application to exploit the vulnerability. An attacker must first login to the system to execute the exploit (Talos).

Microsoft has released security updates to address this vulnerability. The patches are available through KB5039227 for Windows Server 2022 21H2 and 22H2, and KB5039236 for Windows Server 2022 23H2 (Rapid7).
