What is Cross Site Scripting (XSS)
This blog explains how XSS works and how it can be used to steal sensitive information.
Cross Site Scripting, also known as XSS, is a type of cyberattack in which an attacker manipulates a website by injecting malicious script code. This script code is used to deceive website visitors and steal their data. Since the script code can be inserted into web pages, XSS is a dangerous attack because it can compromise the safety of both the website and its visitors.
How does Cross Site Scripting work?
XSS exploits web applications that are insufficiently protected against code injection. It's a type of script injection that allows an attacker to inject malicious code into a web page, enabling the attacker to manipulate the website. The attacker can manipulate the website by having the code execute in the user's browser.
Why do hackers use XSS?
XSS is usually used to steal sensitive information, such as passwords, credit card details, and personal data. It can also be used to redirect traffic to an attacker's website, allowing the attacker to collect information about the website's visitors, such as location data or personal preferences. XSS can also be used to spread malware, giving an attacker access to confidential information.
How do you prevent Cross Site Scripting?
To ensure websites are protected against these attacks, web developers must follow best practices when developing websites. They need to take the most up-to-date security measures, such as using filters to block XSS attacks, and using encryption to protect data. In addition, they should not allow code that can be entered from the outside, such as JavaScript and HTML.
To prevent websites from having security vulnerabilities that enable XSS attacks, web developers also need to be well informed about security risks and best practices in website development. In addition, they need to regularly scan the website to check that no security vulnerabilities are present. Want to know more about continuous pentesting?

Tozetta organized a webinar in which we talk more about the common vulnerabilities from 2023. In this webinar, we discuss, among other things, Cross Site Scripting and how to prevent it. At the bottom of the page, we've included the YouTube link to the webinar.
It's also important for website administrators to regularly update their security software to ensure websites remain protected against XSS attacks. In addition, they should also regularly check all data for potential security risks.
In general, XSS is a dangerous attack, but it can be prevented by taking the right security measures. By taking the right security measures, businesses can be confident that their website is safe from XSS attacks. Having trouble identifying the vulnerabilities mentioned above? Through a pentest, security risks can be reduced and your solutions better protected. How does a pentest work?
