[ Day3 ] Web 小可爱

昨天我们解了 Web 50分的题目,今天要来挑战100分的罗

有人在期待吗??
哈哈我想没有的
我从滑板课下课後立马赶回来写文章
多捧场一下嘛~

logon

The factory is hiding things from all of its users. Can you login as Joe and find what they've been looking at? https://jupiter.challenges.picoctf.org/problem/13594/ (link) or http://jupiter.challenges.picoctf.org:13594

Hints

Hmm it doesn't seem to check anyone's password, except for Joe's?

有人猜到这题在考什麽ㄇ?

cookie

是浏览器的小型文字档,提供网路应用程序储存资料纪录(session, ID)

我们 link 点下去後,出现这张图

我输入 username : kaka
password : 123tty

解果出现下图

再来怎麽办呢?
还记得我们昨天有用右键检视网页原始码

要怎麽让网站知道登入的帐号是不是 Admin?
答对了! 就是 Cookie
我们按右键->检查 (就是常用的 F12啦)
