中國安全公司深信服(Sangfor)近日發現了名為 PrintNightmare 的零日漏洞，允許黑客在補丁完善的 Windows Print Spooler 設備上獲得完整的遠程代碼執行能力，該公司還發布了概念證明代碼。

在 6 月補丁星期二活動日中，微軟發布的安全累積更新中修復了一個類似的 Print Spooler 漏洞。但是對于已經打過補丁的 Windows Server 2019 設備，PrintNightmare 漏洞依然有效，并允許攻擊者遠程執行代碼。

根據概念證明代碼顯示，黑客只需要一些(甚至是低權限)的網絡憑證就可以利用該漏洞進行遠程執行，而且這些憑證在暗網上只需要 3 美元就能買到。這意味著企業網絡又極易受到(尤其是勒索軟件)的攻擊，安全研究人員建議企業禁用其 Windows Print Spoolers。
