其中值得重点关注的可远程利用的服务端漏洞主要包括CVE-2022-26809 Remote Procedure Call Runtime 远程代码执行漏洞，CVE-2022-24491、CVE-2022-24497 Windows Network File System 远程代码执行漏洞。

漏洞描述

CVE-2022-26809 Remote Procedure Call Runtime 远程代码执行漏洞

Remote Procedure Call Runtime 存在远程代码执行漏洞，攻击者可通过构造恶意的 RPC 请求来利用此漏洞。此漏洞的利用无需用户交互，也无需授权，可通过 445 端口被攻击者远程利用，因此被认为是可蠕虫的漏洞。目前此漏洞尚未有公开的细节和利用脚本。

CVE-2022-24491、CVE-2022-24497 Windows Network File System 远程代码执行漏洞

CVE-2022-24491 和 CVE-2022-24497 都是存在于 Windows Network File System 中的远程代码执行漏洞，远程且未经过授权的攻击者可通过发送恶意的 NFS 协议数据包来进行漏洞利用。这两个漏洞只影响启用了 NFS 角色的 Windows 系统，且目前尚未有公开的细节和利用脚本。
