Client-side attacks are complex to mitigate as they abuse the trust between a web server and the users accessing the website. Two such client-side attacks are Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF), which inject malicious scripts into a target system for deeper exploitation of the tech stack or user data theft. In this article, we discuss XSS vs. CSRF attacks and learn typical attack mechanisms, prevention techniques, and differences in how they are orchestrated.
What are XSS and CSRF?
Both CSRF and XSS are client-side attacks that abuse the same-origin policy and exploit the trust relationship between the web application and the victim user.
XSS and Cross-site scripting attacks allow an attacker to compromise the interactions of legitimate users with any vulnerable application.
What is XSS?
XSS vulnerabilities occur in web applications that accept user input and use it in response without encoding or validation. The malicious users craft malicious code and submit it via the input form. The target server includes this script and its response, and the client browser executes it. Since the browser trusts the web server, it grants the malicious script access to cookies, the session token, and other sensitive client information stored locally.
XSS is a well-known attack vector, and the
