●误差概述


5月 14 日，，，微软官方宣布清静更新，，，其中修复了 Windows 系统远程桌面效劳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效劳器的远程桌面效劳端口（默以为 3389），，，无需其他交互，，，即可在目的效劳器上执行恶意代码，，，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模浚�？？？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效劳，，，建议禁用该效劳。。。

开启网络级别身份验证(NLA)

关闭TCP端口3389的毗连，，，或对相关效劳器做会见泉源过滤，，，只允允许信IP毗连。。。
