XSS occurs when an application includes untrusted data in a web page without proper validation or escaping, allowing attackers to execute malicious scripts in a victim’s browser.

Anti-CSRF measures

CSRF forces an authenticated end-user to execute unwanted actions on a web application in which they are currently authenticated. The Exploit gruyere learn web application exploits defenses top

Defensive concepts and secure coding practices Gruyere is instructive not only about attacks but also about defenses developers must adopt:

Before we dive into the exploits, let's understand the playing field. Gruyere is an excellent mirror for the real-world threats detailed in industry-standard lists.

CSRF forces an authenticated end-user to execute unwanted actions on a web application where they are currently authenticated. Exploitation Techniques Security is a moving target

Always sanitize and validate user-supplied text. Use secure coding practices like escaping special characters and implementing a strong Content Security Policy (CSP) to restrict script execution. 2. Client-State Manipulation

Validate input against strict regular expressions to ensure it matches expected formats (e.g., alphanumeric only for usernames). 4. Path Traversal (Directory Traversal)

: Move sensitive state data (like user permissions) from the client-side (cookies/hidden fields) to secure server-side databases. Access Control Learn more XSS occurs when an application includes

Use built-in path utilities to resolve absolute paths and explicitly reject any input containing directory traversal characters.

The vulnerability exists entirely within the client-side JavaScript code, processing unsafe user input and passing it to a dangerous sink (like element.innerHTML ). Defensive Architecture
