[原文]IIS 5.0 and 5.1 allows remote attackers to cause a denial of service (crash) via malformed WebDAV requests that cause a large amount of memory to be assigned.


[CNNVD]Microsoft Internet Information Server WebDAV远程拒绝服务漏洞(MS02-062)(CNNVD-200211-036)

        
        Microsoft IIS是一款HTTP服务程序,IIS 5.0/5.1包含WebDAV组件。WebDAV允许WEB开发队伍和其他工作组可以使用远程WEB服务器共同协作工作。
        IIS 5.0/5.1在为WebDAV请求分配内存时存在问题,远程攻击者可以利用这个漏洞进行拒绝服务攻击。
        由于IIS 5.0/5.1在为WebDAV请求分配内存处理不正确,如果攻击者发送畸形WebDAV请求给服务器,IIS会在服务器上分配一超大的内存给这个请求。通过发送多个相同形式请求,可导致消耗服务器上所有内存而停止对正常请求进行响应。
        此漏洞只有在服务器上运行了索引服务和服务器允许WebDAV请求的情况下才存在。

- 漏洞讨论

A denial of service vulnerability has been reported for Microsoft IIS 5 and 5.1. This vulnerability is related to how IIS allocates memory for WebDAV requests. Any specially crafted WebDAV requests may result in IIS allocating an extremely large amount of memory on the server. Several malformed requests sent to the server will result in the vulnerable system failing to respond to further legitimate requests for service. This vulnerability affects IIS 5.0 and 5.1 only.

This vulnerability was originally described in BugTraq ID 6068. It is now being assigned its own BugTraq ID.

** Reports suggest that numerous hosts have been scanned in an attempt to exploit this vulnerability. Although unconfirmed, this may be the result of a system of automated attacks.
