[原文]Scripting.FileSystemObject in asp.dll for Microsoft IIS 4.0 and 5.0 allows local or remote attackers to cause a denial of service (crash) via (1) creating an ASP program that uses Scripting.FileSystemObject to open a file with an MS-DOS device name, or (2) remotely injecting the device name into ASP programs that internally use Scripting.FileSystemObject.


[CNNVD]Microsoft IIS设备文件本地拒绝服务漏洞(CNNVD-200107-051)

        CVE(CAN) ID: CAN-2001-1243
        
        
        
        Microsoft IIS可能会由本地用户引发拒绝服务攻击,前提是本地用户可以创建一个
        
        .asp文件,而这个.asp文件调用了设备文件。
        
        
        
        这会导致Microsoft IIS停止响应,只有重新启动才能恢复正常工作。
        
        
        
        如果站点自己的asp程序允许用户指定打开的文件,也可能导致拒绝服务发生。

Microsoft IIS is prone to denial of service attacks by local users. This issue is exploitable if the local attacker can create an .asp file which makes calls to various devices names. The local attacker must of course possess the privileges required to create such files.

The end result of exploiting this vulnerability is that the server will crash and a denial of services will occur. The affected services must be restarted to regain normal functionality.

  Dim strFileName, objFSO, objFile

  Set objFSO = Server.CreateObject("Scripting.FileSystemObject")

  Set objFile = objFSO.OpenTextFile(strFileName)

Microsoft IIS is prone to denial of service attacks by remote attackers. This can occur if the remote attack crafts a URL which tries to pass a script parameter that is a device name.

The end result of exploiting this vulnerability is that the server will crash and a denial of services will occur. The affected services must be restarted to regain normal functionality.

- 解决方案

Microsoft's offical response regarding this issue:

"To address this specific issue, the IIS4 and 5 checklists include a recommendation to remove the FSO component - I believe the IIS5 security configuration tool also removes this mapping automatically."

Please see the Credit section for IIS 4 and 5 security checklists.
