Last summer I started learning about information security and hacking. Until now. This will be a detailed story about how I hacked into a server which hosted 40 this is an exact number websites and my findings. A friend messaged me that an XSS vulnerability was found in his website and that he wants me to take a further look. This is an important stage, as I am inclined to ask for him to formally express that I have his permission to perform a full test on his how to hack a website easy application and on the server hosting it.
The answer was positive. It required credentials and since we have neither a username nor a password we move on. Browsing to the website we see that it asks us to login. No problem, we create an account with a dummy e-mail how to hack a website easy, click the confirmation e-mail and log-in after few seconds. The website welcomes us and prompts us to navigate to our profile and update our profile how to hack a website easy. How kind.
Seeing that the website looks custom built, I am inclined to test for an Unrestricted File Upload vulnerability. On my terminal I execute:. The uploader allows the exploit. Of course it has no thumbnail, but that means my file got uploaded somewhere. Here we would expect that the uploader does some sort of processing on the uploaded file, checks its file extension and replaces with the accepted file extension like.
Seeing that the webserver runs perl scripts really, perl? To my huge surprise, the server was not hosting only 1 website, but 40 different ones. You get the how to make baby panties. I limited myself to example. The credentials for the database were there in cleartext. Let these be root:pwned Webiste enough, the server was running MariaDB and I had to resort to this issue before being able to access websote database.
Afterwards we execute:. Here I am morally eebsite to stop, and disclose my findings so far. The potential damage is already huge. Unfortunately I was still apache. Before looking in ways to escalate my privileges to root and be able to cause massive potential damage, I was looking at what other interesting files I could read with my limited user. At that point, I remembered about the open SMB ports.
That meant that there should be how to change your default payment method on paypal folder somewhere that is being shared in the system among users.
Inside all of these directories, there were files of each user of the hosting company. That included all kinds of sensitive data, amongst others:. After looking around for a little longer as apache I decide it is time to go for the big fish, alas get root access. I refer to a popular cheatsheet and start enumerating the system for interesting files.
Due to my digging so far I had already gone through most of these techniques already and did not seem to be able to find something that would increase my foothold.
In the Capture the Flag challenges that I am used to playing, the operating system is usually patched and it is some intentionally misconfigured service that eventually gives you the sought-after root privilege. In the real world however, people do not patch. I found this blogpost which pointed me to test hw the Kernel was vulnerable with the script found here. I instantly wrote an e-mail fully disclosing the details and potential impact of every step as described above, and eebsite the night.
The next day, I got contacted by my friend who came in contact with the company operating the server and was informed that the bug in the file uploader was fixed. One fix I would suggest would be not to use perl in but that is just my opinion, feel free to prove me wrong. Regarding the filesystem, I recommend taking great care in assigning proper file permissions for users, according to the principle of least privilege. That way, even if a jack privileged user like apache gets access, they are not able to read any sensitive files.

More people have access to the internet than ever before. This has prompted many organizations to develop web-based applications that users can use online to interact with the organization.
Poorly written code for web applications can be exploited to gain unauthorized access to sensitive data and web servers. In this tutorial you will learn how to hack websites, and we will introduce you to web application hacking techniques and the counter measures you can put in place to protect against such attacks. Topics covered in this tutorial What is a web application?
What are Web Threats? How to protect your Website against hacks? Website hacking tricks: Hack a Website online! What is a web application? A web application aka website is an application based on the client-server model. The server provides the database access and the business logic.
It is hosted on a web server. The client application runs on the client web browser. Web applications are usually written in languages such as Java, C , and VB. Most web applications are hosted on public servers accessible via the Internet. This makes them vulnerable to attacks due to easy accessibility. The following are common web application threats. SQL Injection — the goal of this threat could be to bypass login algorithms, sabotage the data, etc. Denial of Service Attacks — the goal of this threat could be to deny legitimate users access to the resource Cross Site Scripting XSS — the goal of this threat could be to inject code that can be executed on the client side browser.
Form Tampering — the goal of this threat is to modify form data such as prices in e-commerce applications so that the attacker can get items at reduced prices.
The code can install backdoors, reveal sensitive information, etc. An organization can adopt the following policy to protect itself against web server attacks. SQL Injection — sanitizing and validating user parameters before submitting them to the database for processing can help reduce the chances of been attacked via SQL Injection. Proper configuration of networks and Intrusion Detection System can also help reduce the chances of a DoS attack been successful. Cross Site Scripting — validating and sanitizing headers, parameters passed via the URL, form parameters and hidden values can help reduce XSS attacks.
Form tempering — this can be prevented by validating and verifying the user input before processing it. Code Injection - this can be prevented by treating all parameters as data rather than executable code. Sanitization and Validation can be used to implement this. Defacement — a good web application development security policy should ensure that it seals the commonly used vulnerabilities to access the web server.
This can be a proper configuration of the operating system, web server software, and best security practices when developing web applications. Website hacking tricks: Hack a Website online In this website hacking practical scenario, we are going to hijack the user session of the web application located at www.
We will use cross site scripting to read the cookie session id then use it to impersonate a legitimate user session. The assumption made is that the attacker has access to the web application and he would like to hijack the sessions of other users that use the same application. Refer to this article for more information on how to do that. The login email is This email address is being protected from spambots.
