Is CSRF still possible?

Is CSRF still possible?

Is CSRF Still Possible? Yes. Even with browsers adopting the SameSite by default policy, CSRFs are still possible under some conditions. First, if the site allows state-changing requests with the GET HTTP method, then third-party sites can attack users by creating CSRF with a GET request.

Is XSRF the same as CSRF?

CSRF is also known by a number of other names, including XSRF, “sea surf,” session riding, cross-site reference forgery, and hostile linking. Microsoft refers to this type of attack as a one-click attack in its threat modeling process and many places in its online documentation.

Is CSRF possible without Cors?

First, CORS is intended to “relax” same-origin-policy which is a default that prevents a specific type of CSRF attack. But, same-origin doesn’t apply on all kinds of requests.

Does CSRF work without cookies?

CSRF tokens should not be transmitted using cookies. The CSRF token can be added through hidden fields, headers, and can be used with forms, and AJAX calls. Make sure that the token is not leaked in the server logs, or in the URL.

Can a CSRF attack distinguish between legitimate and forged requests?

Therefore, if the user is authenticated to the site, the site cannot distinguish between legitimate requests and forged requests. The impact of a successful CSRF attack is limited to the capabilities exposed by the vulnerable application and privileges of the user.

What is the SameSite attribute in CSRF protection?

SameSite is a cookie attribute (similar to HTTPOnly, Secure etc.) which aims to mitigate CSRF attacks. It is defined in RFC6265bis. This attribute helps the browser decide whether to send cookies along with cross-site requests.

Which is the best framework for CSRF protection?

It is strongly recommended to research if the framework you are using has an option to achieve CSRF protection by default before trying to build your custom token generating system. For example, .NET has built-in protection that adds a token to CSRF vulnerable resources.

What can a CSRF attack do to you?

If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application.
