Portswigger Lab

Lan link. The lab description says it is vulnerable to a password reset poisoning vulnerability. At first, we reset the password of the wiener user to understand the system structure. Specifying username in the POST /forgot-password request is enough to request a password, if we can manipulate this request with X-Forwarded-Host, the email for username …

Lab link. We see that our lab description contains XSS. At first, we look at the cookie value used in the system. We find a forum on the blog page to organize our XSS attack. Here we first try a basic XSS payload to see if it is XSS. <script>alert(1);</script> We have found our XSS …

Lab link. Persistent cookies are used in sections such as “Remember me”. Some websites keep This cookie in predictable values or simple hashed form. In this Lab, operations are also done through cookies, we will examine this first. We need a hash-type detector to solve the structure in Cookie, you can use whatever you want. …

Lab link. There is a weakness in the system related to 2FA authentication. To understand the structure of the vulnerability, we enter the system with the credentials given to us. If the MFA code is sent incorrectly twice, the system redirects us back to the login page. This makes our brute-force attack fail. For this …

Lab link. On the 2FA login pages, we send the MFA code, which is our last request. We leave only the verify component in the cookie value and make it carlos instead of wiener. When we send the request, we get the information that the MFA code is incorrect, which indicates that the system is …

Lab link. When we send the request, we see that it goes in JSON format and if we make a certain number of mistakes, we are blocked from IP. By sending more than one password in the JSON structure, we can achieve a successful login. We bring our passwords to JSON structure with Sublime text …

Lab link. Certain suspicious accounts can be locked by the system. In this lab, our goal is to find the username first and then the password. We don’t get any time block when we make a few wrong attempts. We move our request to the intruder. To get an account lockout error, we need to …

Lab link. We need to find the password for the user carlos. We know there is a logic flaw, so let’s make a few false entries and try to understand the system. After 3 login attempts, the system displays “You have made too many incorrect login attempts. Please try again in 1 minute(s).” error. We …
