![]() ![]() Refresh the page to successfully logging in. We can manually create the cookie on the login page named “SessionToken” and assign it any value as there is no code to validate our cookie. There is an alternate method to login as the login.js is creating a cookie in case of successfully logging in. Specifically, we will be looking at: What Burp Suite is An overview of the available tools in the framework Installing Burp Suite for yourself Navigating and configuring Burp Suite. Wow! we got access to the page without the credentials. Motasem Introduction We covered the Burp Suite proxy settings in addition to the scope and target settings as part TryHackMe Junior Penetration Tester pathway. ![]() We get the response as expected now change it to anything else or delete “Incorrect Credentials” and again forward the request. Now, as we want to change the response, not the request so choosing Action > Do intercept > Response to the request.įorwarding the request to get the response: Here lies the vulnerability as a user can change the response of /api/login from “Incorrect Credentials” to anything else using BurpSuite and trick the server to run the else part of the code. Till here, everything seems perfect now in the Conditional statement it checks if the response from the server is “Incorrect Credentials” then it will not allow access otherwise, it will set a cookie named “SessionToken” to statusOrCookie and redirect us to the admin panel. ![]() The variable creds take the credentials, and variable response sends them to /api/login for validation, and the statusOrCookie variable takes the response. The function login() in the box is the vulnerable code that will let us bypass the login form. The Burp Suite: Intruder room is for subscribers only. Just enumerating the files associated with the source code shows us an exciting file named login.js containing the function used in the login form on the /admin page. Now no clue on credentials, also brute-forcing is not the solution as mentioned in the hint. Dirsearch Scanĭirectory scanning showed many pages but /admin/ seems interesting. This shows a normal webpage with some information about overpass password manager.There are only two pages linked with homepage which seems usual,so starting a directory scan. Simultaneously starting nikto scan till then but got nothing unusual. EnumerationĪs always starting with a nmap scan.Only two 22 with SSH and 80 with Http are open.Rest are filtered.Initially no clue on SSH so moving to Enumerate Http. Also, using some automated Privilege Escalation scripts like linpeas.sh makes it more interesting. It is worth solving this room as it contains some essential Owasp Top 10 vulnerability, i.e Broken Authentication. Hello, today we are going to solve an exciting room Overpass, which is quite different for me than other challenges. TryHackMe is a free online platform for learning cyber security, using hands-on exercises and labs, all through your browser TryHackMe is a free online platform for learning cyber security, using hands-on exercises and labs, all through your browser Learn. This ability to edit and resend the same request multiple times makes Repeater ideal for any kind of manual poking around at an endpoint, providing us with a nice Graphical User Interface (GUI) for writing the request payload and numerous views (including a rendering engine for a graphical view) of the response so that we can see the results of our handiwork in action.Here is a walkthrough of the TryHackMe room “Overpass.” If you haven’t already completed the challenge, you can do so here. Alternatively, we could craft requests by hand, much as we would from the CLI ( Command Line Interface), using a tool such as cURL to build and send requests. In layman’s terms, it means we can take a request captured in the Proxy, edit it, and send the same request repeatedly as many times as we wish. In short: Burp Suite Repeater allows us to craft and/or relay intercepted requests to a target at will. If you have not used Burp Suite before and have not completed the Burp Basics room, you may wish to do so now before continuing, as this room builds on the foundations covered there. Throughout this room, we'll take a look at the basics of installing and using this tool as well as it's various major components. ![]() Finally, we will encounter a series of examples, including a real-world, extra-mile exercise which we will use to consolidate the more theoretical aspects of the room. SQL injection is a technique through which attackers can execute their own malicious SQL statements generally referred to as a malicious payload. Task 1 Intro Burp Suite, a framework of web application pentesting tools, is widely regarded as the de facto tool to use when performing web app testing. We will be covering how to use Repeater to manipulate and arbitrarily resend captured requests, as well as looking at some of the niftier options available in this awesome tool. This was part of TryHackMe JR Penetration Tester pathway. We covered the basics of the Repeater in Burp Suite and we presented an example using SQL injection scenario. ![]()
