爆破-1

flag在一个长度为6的变量里面

$$a ,可以实现变量覆盖，

hello传入GLOBALS全局变量，$$a可以实现查看全部变量

爆破-2

flag不在变量中

代码审计

“百度杯”CTF比赛 2017 二月场--web 爆破-3 writeup_会下雪的晴天的博客-CSDN博客

说的也很清楚

设置变量nums为0；time为当前时间；whoami的值为：ea
120秒后结束回话
传入变量value的值
创建一个从 “a” 到 “z” 的数组$str_rand
mt_rand()从0-25随机选取数字，整句话得到两个随机字母
whoami需要等于value的前两位，并且value的md5值的第5为开始，长度为4的字符串==0
循环10次输出flag

md5直接那里直接用数组就可以绕过了

先传入ea，左上角会弹出新的随机字母，继续重复即可,手动的时间完全够

include

没错，就是文件包含漏洞
