[原文]** DISPUTED ** RunAs (runas.exe) in Windows 2000 allows local users to create a spoofed named pipe when the service is stopped, then capture cleartext usernames and passwords when clients connect to the service. NOTE: the vendor disputes this issue, saying that administrative privileges are already required to exploit it.

Microsoft Windows 2000 RunAs Service Named Pipe Hijacking Vulnerability (EDBID:21069)

The Windows 2000 RunAs service allows an application or service to be executed as a different user. It is accessed by holding down the shift key and right mouse clicking on an icon, then selecting 'Run as...' from the context menu.

When the RunAs service is invoked, it creates a named pipe for client for communication of credentials (in cleartext).

If the RunAs service is stopped, the attacker can create a named pipe with the same name to which credentials will be communicated when another user tries to use 'RunAs'.

- 漏洞描述

Microsoft Windows 2000 was reported to contain a flaw that may allow a malicious user to read another user's credentials. The issue is triggered when the RUN AS service is stopped, and a malicious user can read the authentication data entered into the RUN AS dialog via a crafted named pipe. However, it requires administrative privileges to create a named pipe making this a non-issue.
