[紧急]微软修复新远程桌面漏洞,涉及Windows 10,2008R2,2012,2016,2019. 2019-08-15
2019年8月14日微软官方发布安全补丁,修复了两个Windows远程桌面服务的远程代码执行漏洞CVE-2019-1181/CVE-2019-1182,这两个漏洞影响了几乎所有目前受支持的Windows系统。此漏洞是预身份验证且无需用户交互,这就意味着这个漏洞可以通过网络蠕虫的方式被利用。利用此漏洞的任何恶意软件都可能从被感染的计算机传播到其他易受攻击的计算机,与2019年5月14日修补的远程桌面服务的远程代码执行漏洞CVE-2019-0708和2017年WannaCry恶意软件的传播方式类似。
经研判,确认漏洞:严重,建议用户立即进行补丁更新处理。

0x02 修复建议
阻塞企业外围防火墙上的TCP端口3389
如果系统上不再需要这些服务,可以考虑禁用
在受支持的Windows 7、Windows Server 2008和Windows Server 2008 R2版本的系统上启用网络身份验证(NLA),这使得攻击者首先需要使用目标系统上的有效帐户对远程桌面服务进行身份验证然后才能利用该漏洞
