Cross-Site scripting occurs when data passed between different websites is vulnerable to injection attacks. Imagine the following scenario: you log in to your online banking website and enter the credentials of your online banking provider. Now, imagine that while entering the credentials of your online banking provider, you are also checking your email or browsing the social media accounts of your online banking provider. The potential damage of such a scenario can be understood by considering the following facts: Possibility of data theft by hackers due to weak passwords and other factors. Possibility of data manipulation by hackers due to weak security settings on your online banking provider’s site. Possibility of data manipulation by hackers due to weak security settings on your email provider’s site. Possibility of data manipulation by hackers due to weak security settings on your social media provider’s site. Therefore, the risk of data manipulation is high when you log in to your email account, browse your social media account, or check your email account. The above scenario illustrates the risk of data manipulation due to cross-site scripting.
How do online banking websites get vulnerable to Cross-Site Scripting?
Cross-Site Scripting (or XSS) occurs when data passed from one website to another is vulnerable to injection attacks. The following are the primary causes of Cross-Site Scripting:
Poorly written code that does not adequately sanitize user input.
A lack of proper domain separation between websites.
A lack of proper server-side validation for data exchanged between websites.
How to identify if your website is vulnerable to Cross-Site Scripting?
The first step to identifying whether your website is vulnerable to Cross-Site Scripting is to identify any web browser's cookies that are attached in the web browser's .ini file. If there are no such cookies, then your site is not vulnerable to Cross-Site Scripting. However, if there are any such cookies, then you must check for the following items:
1) The existence of redirects by using the Referer header and checking for a single "www." in the URL string
2) The presence of a single quotation mark ("), which would indicate that data passed between different websites was vulnerable to injection attacks.
3) The existence of any scripts with domain names that match those in the security settings of your email provider or social media provider. This would imply that data was being injected into these websites by hackers who were exploiting weak security settings on these websites.
4) The existence of any scripts with URLs that match those in your security settings on your online banking provider's site. This would imply that data was being injected into this website by hackers who were exploiting weak security settings on this site.
How Cross-Site Scripting (XSS) Works?
Cross-site scripting, also referred to as XSS, is one of the main reasons behind the vulnerability of websites. With cross-site scripting, data passed between different websites can be vulnerable to injection attacks. This means that malicious code can be injected into a web page in such a way that it will execute any function within the website, causing an abnormal behavior or effect. For example, imagine an attacker who injects malicious code into a website in such a way that when someone visits the website and inputs their username and password (which is stored on the same server), it will automatically send them back to their email account and cause all of their inboxes and drafts to be sent back to their email account.
How to prevent Cross-site scripting?
Cross-site scripting is a type of injection attack that can happen when data passed between different websites is vulnerable to injection attacks. This happens because the data you enter on one website is not always validated properly. So, what can be done to prevent this attack? Well, there are three ways in which cross-site scripting can be prevented:
What Is Cross-Site Scripting?
Cross-site scripting occurs when data passed between different websites is vulnerable to injection attacks. This vulnerability can be exploited by hackers, who use it to steal sensitive information such as passwords, personal data, and credit card numbers. To understand cross-site scripting, consider the following facts: Cross-site scripting occurs when one website sends data to another site without checking that the other site is authenticated and safe. Note: One of the most common methods used by hackers to exploit cross-site scripts is SQL injection.
SQL injection occurs when a hacker injects their own code into a database table of an online form or other website. The code can be used to take over your account with no password required, or it can steal your personal information such as login credentials and credit card numbers.
