IIS4.05and5.0存在漏洞，远程攻击者通过通常包含超大文件扩展名数量的超长和复杂的URL触发拒绝服务，也称”URL中的异常扩展数据”漏洞。

Sending a specially crafted URL containing malformed file extension information to Microsoft IIS 4.0/5.0 will consume CPU usage until it reaches 100% which will halt the program's services. Restarting the application or waiting until the URL is processed will be required in order to regain normal functionality.
