[原文]The shtml.exe component of Microsoft FrontPage 2000 Server Extensions 1.1 allows remote attackers to cause a denial of service in some components by requesting a URL whose name includes a standard DOS device name.


[CNNVD]Microsoft FrontPage服务器扩展shtml.exe远程拒绝服务攻击漏洞(CNNVD-200010-045)

        
        FrontPage服务器扩展是Microsoft的一个产品,包括PWS和IIS版本,可以让网页设计人员方便的直接用FrontPage直接连接到PWS或者IIS上进行网页创作。shtml.exe是FrontPage服务器扩展的组件之一。
        shtml.exe存在一个设计失误,远程攻击者可以利用此漏洞对服务器进行拒绝服务攻击。
        FrontPage服务器扩展存在一个远程拒绝服务漏洞,可能远程关闭一个Web站点上的所有FrontPage操作。通过向shtml.exe提交一个包含DOS设备名(譬如con、aux、prn等)的链接请求,FrontPage 服务器扩展会挂起,不再响应后续的请求。为了恢复正常工作,必须重新启动IIS或者重新启动机器。

Microsoft FrontPage shtml MS-DOS Device Name DoS
Remote / Network Access Denial of Service
Loss of Availability
Exploit Public

- 漏洞描述

Microsoft FrontPage 2000 Server Extensions contain a flaw that allow a remote attacker to create a denial of service. The issue is due to improper sanity checking on URI requests. If a request contains the same character sequence as a MS-DOS device name (COM, PM, AUX, etc), the service will consume significant CPU resources until the GET request times out.

- 受影响的程序版本

Microsoft FrontPage 2000 Server Extensions SR 1.1
- Microsoft Windows 2000 Professional
- Microsoft Windows 95
- Microsoft Windows 98
- Microsoft Windows NT 4.0

- 漏洞讨论

It is possible to remotely crash a system running Microsoft FrontPage Server Extensions by conducting a URL request for a MS-DOS device through shtml.exe. For example, the following URL requests will crash FrontPage Server Extensions:

http://target/_vti_bin/shtml.exe/comX.htm (X being one of 1, 2 ,3, or 4; the device must exist on the target machine)
http://target/_vti_bin/shtml.exe/prn.htm
http://target/_vti_bin/shtml.exe/aux.htm

The device name must have an appended extension in order for the exploit to work. In addition to the HTM extension, ASP will work as well. Restarting IIS or rebooting the system is required in order to regain normal functionality.

Testing has shown that it may require a constant stream of these requests in order to render the server ineffective.
