[原文]NewAtlanta ServletExec ISAPI 4.1 allows remote attackers to cause a denial of service (crash) via (1) a request for a long .jsp file, or (2) a long URL sent directly to com.newatlanta.servletexec.JSP10Servlet.


[CNNVD]NewAtlanta ServletExec/ISAPI JSPServlet远程拒绝服务攻击漏洞(CNNVD-200210-011)

        
        ServletExec/ISAPI是一款运行在Microsoft IIS WEB平台下的Java Servlet/JSP引擎插件,可使用在Microsoft Windows NT/2000/XP系统下的IIS WEB服务程序中。
        ServletExec/ISAPI对用户提交的特殊URL请求没有正确处理,可导致远程攻击者进行拒绝服务攻击。
        远程攻击者可以通过直接请求超长文件名的.jsp文件,或者直接调用JSPServlet及JSP10Servlet,就可以导致IIS崩溃,造成拒绝服务攻击。

ServletExec/ISAPI is a plug-in Java Servlet/JSP engine for Microsoft IIS. It runs with IIS on Microsoft Windows NT/2000/XP systems.

A denial of service condition occurs when the JSPServlet is sent an overly long request either directly or via a request for a JSP file.

It has been reported that this will cause the underlying webserver to crash.

This condition may be the result of insufficient bounds checking, though this possibility has not been confirmed.

/*    This is Exploit code for a vulnerability in NewAtlanta ServletExec ISAPI 4.1.
      ServletExec 4.1 ISAPI is a Java Servlet/JSP Engine for Internet Information
      Server and is implemented as an ISAPI filter.
      Machines running this program is MS IIS server 4 and 5.
	  This code can simple crash the server, successfully preform a DoS attack!
	  It sends a string that servletExec don't like but have to eat, and 
	  this will make the server crash, BIG TIME =)
	  This file assuming the www server is on port 80 and that the servlet engine
	  is located in the /Servlet directory.
