Start your free trial. The OWASP Top 10 includes the top 10 vulnerabilities which are followed worldwide by security researchers and developers. You must have heard or used lots of tools for penetration testing, but to use those tools, you must have a vulnerable web application.

To enter the world of security, you must have hands-on experience finding bugs and vulnerabilities in a web application. Practicing your skills always help you in your career and professional growth. If you are a beginner, then you must test your skills before entering the professional world: it allows you to understand the procedures and methods of securing web apps. If you are a teacher, then you can show your students how things get done: this will help you to evaluate yourself where you stand and which areas you need to improve more.

In short, you must practice your skills before facing real-world security scenarios. Practice will count as an experience that is eventually going to benefit you in the long run. I am going to discuss top five broken or vulnerable web applications which you can use to test or practice your skills, and and which you can easily host at localhost.

It has three levels of security: Low, Medium, and High. Each level of security demands different skills. Developers have decided to share its source code, too, so that security researchers can see what is going on at the backend.

Researchers can also use their various tools to capture packets, brute force, and other such tactics on DVWA. One should try to exploit this application completely. You can easily reset database if you want to start it over again. You can simply download DVWA from here. Badstore : Badstore is one of the most vulnerable web application on which security researchers can practice their skills. Now open your favorite browser and enter that same IP in the address bar. You will see that the Badstore Webpage is now displayed on your screen.

I looked at this a while ago and found that the underlying xml libraries in current distros block attacks like the one you show here. You have to set a flag in PHP to enable them but even with that set, when it gets passed down to the lower levels, the injection gets dropped.

Things may have changed since then, but at the time, it wasn't possible do this through PHP on a Linux box. We use optional third-party analytics cookies to understand how you use GitHub. Learn more. You can always update your selection by clicking Cookie Preferences at the bottom of the page.

Username: admin Password: password "password" is the default password for user admin. Instructions: whoami This command prints the username for the effective userid. If the username was root, then we would be in full control; however, the username is apache.

In this case, apache is pretty well protected. Explore Process and Directory Credentials.

Instructions: ps -eaf grep http Typically, the Apache web server processes will run with a daemon called httpd. This actually tells us a lot. It tell us the exact path of where the NetCat command was executed from in Section 6, Step 2. If this directory was owned by apache instead of root we could do some web graffiti and many other things. Unfortunately, the apache username only has world read and execute permissions. Notice, there is a config directory.

Config directories are important because they contain database credential information. The config. Create a new user in dvwa. Replace Gray with your Last name.

This hack is even more alarming, because you will now be able to add a user that has full privileges for all databases on this machine. Views: Background Information. Section 2: Login to Fedora Section 6: Command Execution.

Section 8: Login to BackTrack. Section Mysql Exploration. Section Proof of Lab.For example, this vulnerability can be used to read arbitrary files from the server, including sensitive files, such as the application configuration files.

So far, major vulnerabilities like SQL injection and Command injection have been playing a major role on the web application attacks. But XXE is also a major critical bug that helps the attacker gain access to the server itself. This vulnerability is an important one to understand because it exists by default for many popular XML parsers.

Extensible Markup Language XML is a feature rich and widely used information exchange format and standard. This is helpful when the entity value is used multiple times. So far, the third type of entities has been most frequently attacked except for DoS : using various files of a file system as a source of an external entity, it was possible not always to read files of the file system via data output in XML or error output. Besides, it was possible to conduct DoS attacks, brute force the content of a parsed entity, read files via a Document Type Declaration DTDwhich, if error output was enabled, allowed displaying the content of the read file.

XML 1. The standard defines a concept referred to as an entity, which is a storage unit of some type. There are different types of entities, but the one we're focusing on is externally referenced.

External entities are valuable to attackers because they can access local or remote content via declared system identifiers, which are a more critical attack on the web application. We must instead entice the application server to 'send us' the response. Upon receiving user-supplied requests, application servers parse the provided data and process it to perform some action.

Examples include:. Unfortunately, however, XML parsers are often times misconfigured and enable the processing of external XML entities when they did not intend to. In addition, no sort of input validation occurs, resulting in the ability to reference any content referenced by an entity. This misconfiguration can result in the ability to access local system resources.

Proof of concept:. Port Scanning process is done the network IP address using nmap for enumeration process. In the above image, we can see that the Ports 21,22,80 has been enumerated with useful information.

How to install XAMPP on Ubuntu 20.04 / Ubuntu 18.04 (Linux)

Port 21 FTP has an anonymous FTP Login, which is a useful piece of information were we can log in without using the password and grab the test. After logging into the ftp using anonymous login, we can clearly see a test. We clearly see that the test. Then open the target IP over web browser. When I found nothing on port 80, then I thought of using DirBuster so I was able to enumerate certain pages on the web directory brute force attack on the application.

Accessing the hosts. So, searched in Google for hosts which were related to It means that test. Add the XML content to the repeater and wait for a response to show the result. This clearly shows a successful attack and also enumerated two local usernames.

Finally, we got the ssh private key successfully, copy the key and save it as a text file. The impact of this vulnerability shows that it is very dangerous, as it allows the attacker to gain complete access and take privilege over the system and perform denial of service attack on the server, etc.

Encode the user input in such a way that entities cannot be defined through user input. Use less complex data formats, such as JSON, and avoiding serialization of sensitive data. Patch or upgrade all XML processors and libraries in use by the application or on the operating system. Implement the positive whitelisting server-side input validation, filtering or sanitization to prevent hostile data within XML documents, header or nodes.

XXE is not a new vulnerability but an existing one that has gained more popularity in recent years on a web application.

Exploiting The Entity: XXE (XML External Entity Injection)

A successful XXE injection attack could result in massive damages on both security and business functionalities. Few better ways to control XXE attacks include.Please record your IP address.
