●误差概述
5月 14 日,微软官方宣布清静更新,其中修复了 Windows 系统远程桌面服务中保存的远程代码执行误差(CVE-2019- 0708)。攻击者在远程且未经授权的情形下,通过发送全心结构的恶意数据包到目的服务器的远程桌面服务端口(默以为 3389),无需其他交互,即可在目的服务器上执行恶意代码,获取系统权限。
直至 9 月 7 日,开源的误差使用框架 metasploit-framework 新增了此误差的使用�?椋╟ve_2019_0708_bluekeep_rce),误差使用工具最先扩散,已经造成蠕虫级的清静威胁。由于可以造成远程代码执行的误差使用剧本已经果真,加上此误差自己具有可蠕虫撒播的性子,有可能会导致类似之前的 WannaCry 蠕虫清静事务爆发,因此现在仍未做误差修复的用户需尽快更新微软官方的清静补丁。

暂时解决计划:
若用户不需要用到远程桌面服务,建议禁用该服务。
开启网络级别身份验证(NLA)
关闭TCP端口3389的毗连,或对相关服务器做会见泉源过滤,只允允许信IP毗连。
