What is CSRF (Cross-site request forgery )

Cross-site request forgery

 CSRFTester (CSRF Vulnerability Tester) :: Tools

 

OWASP CSRFTester is a tool for testing CSRF vulnerability in websites. Just when developers are starting to run in circles over Cross Site Scripting, the 'sleeping giant' awakes for yet another web-catastrophe. Cross-Site Request Forgery (CSRF) is an attack whereby the victim is tricked into loading information from or submitting information to a web application for which they are currently authenticated. The problem is that the web application has no means of verifying the integrity of the request. The OWASP CSRFTester Project attempts to give developers the ability to test their applications for CSRF flaws.

Cross-site request forgery 

Description

Description

Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF or XSRF, is a type of malicious exploit of a website where unauthorized commands are submitted from a user that the web application trusts.

What is CSRF example?

In a successful CSRF attack, the attacker causes the victim user to carry out an action unintentionally. For example, this might be to change the email address on their account, to change their password, or to make a funds transfer.                                     

How does CSRF token work?

This token, called a CSRF Token or a Synchronizer Token, works as follows: The client requests an HTML page that contains a form. ... When the client submits the form, it must send both tokens back to the server. The client sends the cookie token as a cookie, and it sends the form token inside the form data.    

What is CSRF and how do you prevent it?

An attacker can launch a CSRF attack when he knows which parameters and value combination are being used in a form. Therefore, by adding an additional parameter with a value that is unknown to the attacker and can be validated by the server, you can prevent CSRF attacks.                                              

What is XSS and CSRF?

What is the difference between XSS and CSRF? Cross-site scripting (or XSS) allows an attacker to execute arbitrary JavaScript within the browser of a victim user. Cross-site request forgery (or CSRF) allows an attacker to induce a victim user to perform actions that they do not intend to.
