Stay ahead of the game and explore these hidden gems to bolster your web application security arsenal.

What is XSS (Cross-Site-Scripting) 

XSS (Cross-Site Scripting) is a type of security vulnerability that allows an attacker to inject malicious code into a trusted website. This code can then be executed by the website’s users, allowing the attacker to steal their data, hijack their session, or perform other malicious actions.

Here’s an example of how an XSS attack might work:

An attacker visits a website that allows users to post comments.

The attacker enters a malicious comment that contains JavaScript code.

The website’s code does not properly validate or escape the user input, so the malicious code is executed when another user visits the page and sees the comment.

The malicious code can then steal the user’s data, hijack their session, or perform other malicious actions.

There are two main types of XSS attacks:

• Reflected XSS attacks occur when the malicious code is reflected back to the user in the response from the web server. For example, this could happen if the website displays user comments without properly escaping them.
• Stored XSS attacks occur when the malicious code is stored on the web server and is then executed by other users who visit the page. For example, this could happen if the website allows users to save comments or other content that contains malicious code.

XSS attacks can be very difficult to prevent, but there are a number of things that website developers can do to mitigate the risk, such as:

Validating and escaping all user input before it is displayed on the page.

Using a web application firewall (WAF) to block known XSS attacks.

Keeping the website’s software up to date with the latest security patches.

If you think you may have been the victim of an XSS attack, there are a few things you can do:

Change your passwords for all of your online accounts, especially those that you used on the website where you may have been attacked.

Monitor your accounts for any unauthorized activity.

Report the attack to the website’s security team.
