远程桌面协议(RDP, Remote Desktop Protocol)是一个多通道(multi-channel)的协议,让用户(客户端或称“本地电脑”)连上提供微软终端机服务的电脑(服务器端或称“远程电脑”)是大部分的Windows都有客户端所需软件,RDP服务默认监听本机3389端口。
根据MSRC公告显示,本漏洞为RDP服务远程代码执行漏洞,未经认证的恶意攻击者通过向目标主机RDP服务所在端口发送精心构造的请求,即可在目标主机执行任意代码。该漏洞利用门槛低,危害大且攻击者可通过该漏洞横向蠕虫传播,感染大量主机,危害效果可堪比2017年WannaCry等具备勒索能力的恶意程序。

若用户暂不方便安装补丁更新,可采取下列临时防护措施,对此漏洞进行防护。
1. 若用户不需要用到远程桌面服务,建议禁用该服务。
2. 在主机防火墙中对远程桌面TCP 端口(默认为 3389)进行阻断。
3. 启用网络级认证(NLA),此方案适用于Windows 7, Windows Server 2008, Windows Server 2008 R2。
