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。
