      三、漏洞原理

Microsoft Windows是美国微软公司发布的视窗操作系统。远程桌面连接是微软从Windows 2000 Server开始提供的组件。

2019年8月13日,微软发布了安全更新补丁,其中修复了4个远程桌面服务远程代码执行漏洞, CVE编号分别为:CVE-2019-1181、CVE-2019-1182、CVE-2019-1222、CVE-2019-1226。其中 CVE-2019-1181 和 CVE-2019-1182 这两个漏洞和先前的 BlueKeep(CVE-2019-0708)一样,属于“可蠕虫传播的”漏洞。

利用该漏洞远程且未经身份验证的攻击者,向目标服务端口发送恶意构造请求,无需进行用户交互操作,即可获取目标系统的权限并执行任意代码。利用该漏洞,存在被不法分子利用进行蠕虫攻击的可能。
