Don't expect it to be quite so easy in real life, but this should hopefully give you an idea of the kind of situation in which Burp Proxy can be useful. This process is shown in the GIF below :įinally, press the "Forward" button to send the request. After pasting in the payload, we need to select it, then URL encode it with the Ctrl + U shortcut to make it safe to send. With the request captured in the proxy, we can now change the email field to be our very simple payload from above: alert("Succ3ssful XSS"). It does this by providing the ability to capture and manipulate. Submit the form - the request should be intercepted by the proxy. Burp Suite is a framework written in Java that provides a great package of tools for penetration testing of web and mobile apps. Burp Suite is the industry standard tool for web application hacking, and is essential in any web penetration test. ![]() For example: as an email address, and "Test Attack" as a query. Now, enter some legitimate data into the support form. First, make sure that your Burp Proxy is active and that the intercept is on. Let's focus on simply bypassing the filter for now. There are a variety of ways we could disable the script or just prevent it from loading in the first place. You should find that there is a client-side filter in place which prevents you from adding any special characters that aren't allowed in email addresses :įortunately for us, client-side filters are absurdly easy to bypass. root.Try typing: alert("Succ3ssful XSS"), into the "Contact Email" field. In order to use the exploit, create a python file and paste the codes in the website above and then run it.Īfter entering the username, now we are root! Now let’s get the root flag. When I googled for that particular situation, I encountered this website. We have access to all directories except the root directory, but we need to access that one. Now it’s time to escalate our privileges, firstly let’s check what privileges we have. We logged in the SSH, now let’s read the user flag. When we open the file there is a message that gives us username and SSH password, so let’s login. Steghide extract -sf cute-alien.jpg steghide Now by using the text that we have just decoded (“Are***”), let’s try to login. To see the content we are asked a password. Question 1 In the Burp Suite Program that ships with Kali Linux, what mode would you use to manually send a request (often repeating a captured request numerous times) Walkthrough: When putting together an effective search, try to identify the most important key words. Remember we were given a jpg file, let’s check it out by using the steghide tool. We can decode it by using any online decoder. agentrĪ part of the text is given in base64 format. When we enter the password and extract the file we encounter such content. Now let’s start cracking the hash with the john tool. When we examine the cutie.png file with the binwalk tool, we see that there are 3 files hidden in the picture. We have 3 files on the server, let’s check whether we can find something valuable. Now by putting the information that we have gathered to the filezilla we connect to the FTP server. When we launch the tool, we get the result. l parameter refers to username, -P parameter refers to wordlist. As it’s asked us to find out the FTP servers’ password we are going to perform a brute force attack against the FTP server in the target by using the username that we have gathered. So we have found the user that is going to be targeted. In the page that we were directed there is a note about a weak password belonging to the agent ch***. useragent Hash cracking and brute-force agentC When we change the “User-Agent” value in the third line to the “C” we are directed to another agent’s page. In order to change the request that is being sent to the target, we refresh the website page by entering the Proxy>Intercept tab in the Burp Suite.So we see the request that was wanted to change. anasayfaĪs you can see above the screen shot, it’s asked us to change the user-agent request which is being sent to the target to our codename by using Burp Suite. We have the 80th port running so we have a website we can go through. These are the ports 21 (FTP), 22 (SSH) and 80 (HTTP). In order to gather information about the target we perform an “nmap” scan.Īs we have observed there are 3 ports up. Submit the form - the request should be intercepted by the proxy. For example: 'pentesterexample.thm' as an email address, and 'Test Attack' as a query. ![]() Hello everyone, in this article we’ll be solving the room named “Agent Sudo”. First, make sure that your Burp Proxy is active and that the intercept is on. ![]()
