●漏洞概述


5月 14 日，微軟官方發布安全更新，其中修復了 Windows 系統遠程桌面服務中存在的遠程代碼執行漏洞（CVE-2019- 0708）。攻擊者在遠程且未經授權的情況下，通過發送精心構造的惡意數據包到目標服務器的遠程桌面服務端口（默認為 3389），無需其他交互，即可在目標服務器上執行惡意代碼，獲取系統權限。


直至 9 月 7 日，開源的漏洞利用框架 metasploit-framework 新增了此漏洞的利用模塊（cve_2019_0708_bluekeep_rce），漏洞利用工具開始擴散，已經造成蠕蟲級的安全威脅。由于可以造成遠程代碼執行的漏洞利用腳本已經公開，加上此漏洞本身具有可蠕蟲傳播的性質，有可能會導致類似之前的 WannaCry 蠕蟲安全事件發生，因此目前仍未做漏洞修復的用戶需盡快更新微軟官方的安全補丁。

臨時解決方案：


若用戶不需要用到遠程桌面服務，建議禁用該服務。

開啟網絡級別身份驗證(NLA)

關閉TCP端口3389的連接，或對相關服務器做訪問來源過濾，只允許可信IP連接。
