基础关

第一题

网址：http://lab1.xseclab.com/base1_4a4d993ed7bd7d467b27af52d2aaa800/index.php

第二题

给了密文xrlvf23xfqwsxsqf ，需要我们再加密一次，经过查询这是rot13编码，再加密一次得到keyis23ksdjfkfds

第三题

给出了base64加密的密文，需要我们不断解密，写个脚本

第四题

给出了md5加密的密文，直接扔到https://cmd5.org/解密得bighp

第五题

网址：http://lab1.xseclab.com/base1_0ef337f3afbe42d5619d7a36c19c20ab/index.php

题目说只让外国人访问，用burp抓包看到头部看到Accept-Language: zh-CN,zh;q=0.9字段

尝试将zh-CN,zh;删除，得到key

第六题

网址：http://lab1.xseclab.com/base6_6082c908819e105c378eb93b6631c4d3/index.php

只有HAHA浏览器才能访问页面，浏览器相关信息在User-Agent字段中体现，利用burp抓包在User-Agent字段添加HAHA即可得到key

第七题

网址：http://lab1.xseclab.com/base7_eb68bd2f0d762faf70c89799b3c1cc52/index.php

key在响应头部字段中

第八题

网址：http://lab1.xseclab.com/base8_0abd63aa54bef0464289d6a42465f354/index.php

源代码显示访问http://lab1.xseclab.com/base8_0abd63aa54bef0464289d6a42465f354/search_key.php，可是却跳转到http://hacklist.sinaapp.com/base8_0abd63aa54bef0464289d6a42465f354/index_no_key.php

明显有重定向

用burp抓包查看http://lab1.xseclab.com/base8_0abd63aa54bef0464289d6a42465f354/search_key.php返回信息

访问http://hacklist.sinaapp.com/base8_0abd63aa54bef0464289d6a42465f354/key_is_here_now_.php

key: ohHTTP302dd

第九题

网址：http://lab1.xseclab.com/base9_ab629d778e3a29540dfd60f2e548a5eb/index.php

burp抓包将Cookie: Login=0修改成Cookie: Login=1

key is: yescookieedit7823789KJ

第十题

网址：http://lab1.xseclab.com/base10_0b4e4866096913ac9c3a2272dde27215/index.php

在控制台中修改input标签的max-length属性值，修改为1000，然后随便post四位数字以上即可

key is 768HKyu678567&*&K

第十一题

网址：http://lab1.xseclab.com/base11_0f8e35973f552d69a02047694c27a8c9/index.php

要求本地访问，用burp抓包添加X-Forwarded-For:127.0.0.1

这里服务器出问题了，直接给出了源代码和key is ^&*(UIHKJjkadshf

第十二题

网址：http://lab1.xseclab.com/base12_44f0d8a96eed21afdc4823a0bf1a316b/index.php

尝试了admin.php,login.php等都返回404，试着访问robots.txt，发现文件/9fb97531fe95594603aff7e794ab2f5f/

访问，提示you find me,but I am not the login page. keep search.

尝试http://lab1.xseclab.com/base12_44f0d8a96eed21afdc4823a0bf1a316b/9fb97531fe95594603aff7e794ab2f5f/login.php

脚本关

第一题

网址：http://lab1.xseclab.com/xss1_30ac8668cd453e7e387c76b132b140bb/index.php

重定向，burp抓包即可得key is : yougotit_script_now

第二题

网址：http://lab1.xseclab.com/xss2_0d557e6d2a4ac08b749b61473a075be1/index.php

要求我们2秒内计算出值，不然再刷新页面就换成别的算式

写个脚本计算即可

import requests

while True:
    url = "http://lab1.xseclab.com/xss2_0d557e6d2a4ac08b749b61473a075be1/index.php"
    s = requests.Session()
    r = s.get(url)
    match = re.search(r'\s(.*)=<input',r.text)
    result = eval(match.group(1))
    data = {
        'v':result,
        'submit':'提交'
        }
    r = s.post(url,data=data)
    if 'key' in r.text:
        print(r.text)
        break

第三题

输入null即可
