At the same time user click on malicious like from junked email (that sent by the attacker). For example, a user is transferring fund from one account to another account and trusted connection established between the user and bank site. Mostly this is done through creating a forged site and it internally hits the genuine site and by using already established user session, an attacker is done some malicious activity. The example of CSRF is unauthorized fund transfers, data theft etc. This kind of attack can be destroying both client relation and business. The site processes this information believe that this is coming from a trusted source. In this method of attack, attacker copies forge as a trusted source and send the data to the site. It also is known as Session riding and pronounced as XSRF. we can put the validation (client and server-side both) that prevent the malicious data that harming a website. Input Validation: Some time HTML character does make sense for user input. Using UrlEncode and UrlDecode method of class, we can encode and decode the URL with ASp.net code 2.0 and above version. The XSS attack can be possible on query string data due to it is not encoded. The using directive, we can apply encoding rule to the variable.Įncoding the URL: Many applications use Query String to transfer the data from one page to another page. ![]() The Razor engine automatically encode all the inputs so that the script part which adds as any field is never executed. It means that encode the HTML that is stored. ![]() Sanitizing user input: This is helpful to prevent XSS attack on site that allows HTML markup as input. For example, some malicious script can be injected to site in any input field such as comment field and the victim views this page in a browser, the script will run into the browser.įollowing are some solutions to prevent XSS. In stored XSS, the attacker injects the script which stored into the target application permanently. Document Object Model (DOM) Based XSS is an advanced type of XSS attack and it is possible when the client script generates DOM by using provided data. Here, an attacker may inject the payloads (also refer as metadata) to the victim so that the payload script is part of request sent to the webserver and reflected with HTTP response. Reflected XSS is the most common type of XSS vulnerability. There are mainly three types of XSS vulnerabilities: Reflected XSS, DOM-based XSS, and Stored XSS. Types of Cross-Site Scripting (XSS) vulnerabilities In XSS, mostly attack happened via the input field, query string, request headers. It is different from another web attack like SQL injection that does not directly target web app. It is kind of computer security vulnerability found in web application that allows attackers to inject client-side scripts or malicious code into web pages which are viewed by the other users. Improper Authentication & session managementĭo not use components with Known Vulnerabilities In this article, I will cover the following points In this article, I have explained about 10 points that need to consider before start application development.
