中国安全公司深信服（Sangfor）近日发现了名为 PrintNightmare 的零日漏洞，允许黑客在补丁完善的 Windows Print Spooler 设备上获得完整的远程代码执行能力，该公司还发布了概念证明代码。
在 6 月补丁星期二活动日中，微软发布的安全累积更新中修复了一个类似的 Print Spooler 漏洞。但是对于已经打过补丁的 Windows Server 2019 设备，PrintNightmare 漏洞依然有效，并允许攻击者远程执行代码。
根据概念证明代码显示，黑客只需要一些（甚至是低权限）的网络凭证就可以利用该漏洞进行远程执行，而且这些凭证在暗网上只需要 3 美元就能买到。这意味着企业网络又极易受到（尤其是勒索软件）的攻击，安全研究人员建议企业禁用其 Windows Print Spoolers。
