Critical & Important漏洞概述
部分 Critical 及Important 漏洞描述如下：
这两个漏洞是由程序对cmdlet参数的验证不正确造成，经过身份验证的攻击者利用该漏洞可在无需用户交互的情况下实现远程代码执行。
官方评级 Critical，CVSS:3.0 9.1/8.2
CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C
http://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-17132
http://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-17142
该漏洞允许经过身份验证的攻击者在 SharePoint Web应用程序服务器上执行任意 .NET 代码。在其默认配置中，经过身份验证的SharePoint用户能够创建提供必要权限的站点，而这些权限恰好是发起攻击的先决条件。
官方评级 Critical，CVSS:3.0 8.8/7.7
CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C
http://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-17121
能够在Hyper-V客户机上执行特制软件的攻击者，通过向Hyper-V宿主机发送vSMB数据包，可能在Hyper-V宿主机上执行任意代码。
官方评级 Critical，CVSS:3.0 8.5/7.4
CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C
http://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-17095
漏洞由程序对cmdlet参数的验证不正确造成，经过身份验证的攻击者利用该漏洞可实现远程代码执行。
官方评级 Important，CVSS:3.0 8.4/7.6
CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C
http://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-17144
利用该漏洞，本地攻击者运行特制的应用程序可实现特权提升。能够通过SMBv2访问脆弱系统的远程攻击者可以通过网络发送特殊设计的请求，利用漏洞在目标系统上执行代码。
官方评级 Important，CVSS:3.0 7.5/6.5
CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C
