What are CSRF exploits and how can they be prevented?

CSRF, or Cross-Site Request Forgery, is an attack that tricks a user into executing unwanted actions on a web application where they're authenticated. To prevent CSRF, you can use anti-CSRF tokens, same-site cookies, and ensure proper validation of requests.

Can you explain how anti-CSRF tokens work?

Anti-CSRF tokens are unique, secret values generated by the server and sent to the client. When the client submits a request, it includes this token, allowing the server to verify that the request is legitimate and originated from the authenticated user.

What are some common vulnerabilities that CSRF exploits target?

CSRF exploits typically target actions like changing account settings, making purchases, or submitting forms, as these actions can have significant consequences if performed without the user's consent.

How can developers test their applications for CSRF vulnerabilities?

Developers can use tools like OWASP ZAP or Burp Suite to simulate CSRF attacks and check if their applications are vulnerable. Additionally, reviewing code for proper token implementation is crucial.
