natas solution(0-5) 这是一个关于web安全的闯关游戏，通过闯关学习相关知识 Natas teaches the basics of serverside web-security. Each level of natas consists of its own website located at http://natasX.natas.labs.overthewire.org, where X is the level number. T
Overthewire level 27 to level 28 这一关和之前不一样，并没有给我们源码信息，稍微加大了一点难度。 题目给我们的信息很简单，一个搜索框，搜索后会返回一些笑话。 第一步 猜测 输入字符串a，观察网络请求，发现网络请求经历了两步，第一步是post传输原本的请求，第二步是重定向到另外一个get的

Overthewire level 14 to level 15 这一关需要我们输入用户名和密码来获取15关的密码，网页源代码如下 if(array_key_exists("username", $_REQUEST)) { $link = mysql_connect('localhost', 'natas14', '<censored>'); mysql_select_db('natas1
