[原文]Buffer overflow in ASP Server-Side Include Function in IIS 4.0, 5.0 and 5.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via long file names.


[CNNVD]Microsoft IIS ASP SSI远程缓冲区溢出漏洞(MS02-018)(CNNVD-200204-023)

        
        Microsoft IIS(Internet Information Server)是MS Windows系统默认自带的Web服务器软件。
        IIS 4.0、5.0和5.1在处理ASP SSI(服务端包含)存在逻辑检查和缓冲区溢出漏洞,允许远程攻击者得到主机的本地访问权限。
        产生原因是由于在 SSI(服务端包含)的一个安全检查有错误。某些情况下,用户的网页请求能正确地通过在ASP脚本中嵌入文件并处理来完成。在处理嵌入请求之前,IIS会对用户指定的文件名进行检查,以确保文件名有效且其大小能放入一个静态缓冲区。但是,某些情况下,攻击者可以用某种方式提交一个伪造的超长文件名并能通过安全检查,从而导致缓冲区溢出。
        成功地利用这个漏洞,对于IIS 4.0,远程攻击者可以获取SYSTEM权限;对于IIS 5.0/5.1攻击者可以获取IWAM_computername用户的权限。

- 漏洞信息

3320
Microsoft IIS ASP Server-Side Include Buffer Overflow
Local Access Required, Remote / Network Access Input Manipulation
Loss of Confidentiality, Loss of Integrity, Loss of Availability
Exploit Unknown

- 漏洞描述

A remote overflow exists in a safety check that IIS perfoms during server-side includes (SSI). IIS performs this safety check to ensure that a client-specified file is valid. It is possible to specify an invalid filename in such a way that bypasses the safety check. With a specially crafted URL, an attacker can cause either a DoS or the execution of arbitrary code, resulting in a loss of confidentiality, integrity, and/or availability.

- 解决方案

Install Patch Q319733, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): 1. Disable ASP - Version 1.0 of the IIS Lockdown Tool disables ASP by default, and version 2.1 disables ASP if "Static Web Server" is selected. 2. The URLScan tool can be used to prevent code execution, but not the DoS.
