[CNNVD]Microsoft Windows 2000网络连接管理器权限提升漏洞(MS02-042)(CNNVD-200209-017)

        
        Microsoft Windows 2000是微软发布的非常流行的操作系统,网络连接管理器(NCM)是其中的一个组件,允许控制主机系统所管理的所有网络连接。
        根据设计,如果同Windows 2000主机系统创建了网络连接的话,NCM就会调用处理器例程,该例程应在用户的安全环境中运行。但是,本地攻击者可以创建并安装恶意的自定义处理器例程,一旦创建了调用该例程的网络连接的话,非特权用户就可以以本地系统的权限运行处理器例程,导致完全控制系统。

- 解决方案

Download and install Patch Q326886 from Microsoft: Best practices suggest that unprivileged users not be allowed to interactively log onto business-critical servers. If this recommendation has been followed, machines such as domain controllers, ERP servers, print and file servers, database servers, and others would not be at risk from this vulnerability.
