渔人杯

神仙姐姐

点击拜 ，抓包发现get请求了/sx.php

返回如下

{"code":0,"num":1,"flag":"ctfsh0w-f1ag-n0t-h3r3-th1s-msg-just-a-j0ke-}{"}

在repeater重复请求，发现num递增

用脚本批量跑结果，第400次出结果

import requests
url="http://66e970ac-0452-4301-8222-70c49b8680d5.challenge.ctf.show/sx.php"
cookies={"PHPSESSID":"66est1o3vjvfga1dffumj3tec2"}
while(True):resp = requests.get(url, cookies=cookies)if "j0ke" not in resp.text:print(resp.text)break

{“code”:0,“num”:400,“flag”:“ctfshow{591a6b5d-1f0e-4223-a590-442fc6b20f96}”}

题目的hint是想要啥就有啥

post了一个json格式的数据

？？？测试没有任何漏洞，看wp提示的是直接问？嗯，很脑洞，建议下次直接放misc里

懒，写了个脚本跑结果

import re
import requests
flag=""
find = re.compile('flag第.*?位是(.?)', re.S)
url="http://60f8d00c-64be-4709-88a0-d52a1c750e14.challenge.ctf.show/"
try:for i in range(1,100):data={"wish":f"flag第{i}位是什么？"}resp = requests.post(url, data=data)# print(resp.text)flag+=find.findall(resp.text)[0]
except:print(flag)
