浅谈Http Put方法的利用

浅谈Http Put方法的利用 天翼 前几天发现我比较喜欢的一个论坛在主页上挂了类似QQ弹窗广告形式的欺骗连接，随手便对网站进行了探测，发现该网站存在Http put方法上传漏洞，经过测试可以被修改主页，删除目录文件等。下面就和大家分享一下本次渗透的乐趣。 首先给大家推荐一个小工具，天阳网络的小王大哥写的WebDavScaner。下图为扫描后截图。 图一webdavscaner 在扫描探测完毕之后，发现该站点存在”Http Put方法站点篡改漏洞”。该漏洞可能会在Web服务器上运行远程命令（这通常意味着完全破坏服务器及其内容）。可能会在Web 服务器上上载、修改或删除Web 页面、脚本和文件。 这个漏洞危害这么大，我们来看看在此能把这个漏洞应用到什么程度吧。 针对Http put漏洞的产生这里先简单介绍一下，这个漏洞主要是因为WebDav配置不严导致我们的应用程序可直接对WebServer进行读写。

WebDav请求的格式中提供了一组可供客户端与服务器通讯的方法，并指定响应（从服务器返回发出请求的客户端）的格式。WebDav完全采用此规范中的所有方法，扩展其中的一些方法，并引入了其他可提供所描述功能的方法。主要的方法包括 WebDAV 请求的一般结构遵循 HTTP 的格式并且由以下三个组件构成： 下面，我们开始提交信息，就是我们telnet到网站的80端口，输入提交信息等，但是在我们telnet的时候只能输入一行信息就自动退出了，那有没有什么好的办法呢?这里我们使用网络瑞士军刀NC。打开cmd窗口，输入：nc –vv https://www.wendangku.net/doc/8f16674179.html, 80 。然后输入请求的数据包头信息和测试页信息并提交,这里注意提交信息需要区分大小写和空格，PUT之后填写路径名称。 表一提交的代码
