Typically, CSRF attacks are possible against web sites that use cookies for authentication, because browsers send all relevant cookies to the destination web site. However, CSRF attacks are not limited to exploiting cookies. For example, Basic and Digest authentication are also vulnerable.
Why are CSRF attacks possible against web apps?
CSRF attacks are possible against web apps that use cookies for authentication because: Browsers store cookies issued by a web app. Stored cookies include session cookies for authenticated users.
How to send CSRF tokens from server to client?
It seems common (e.g. in AngularJS, Django, Rails) to send the CSRF token from server to client as a cookie (i.e. in a Set-Cookie header), and then have Javascript in the client scrape it out of the cookie and attach it as a separate XSRF-TOKEN header to send back to the server.
Is the CSRF countermeasure for file downloads valid?
The CSRF countermeasure in the previous point ensures that the download request is valid but CSRF is not concerned with repeating multiple valid requests. For example, you would have this same issue if an attacker implemented an AutoIt script that repeatedly clicked the download button.
How are cross site request forgery ( CSRF ) attacks used?
Your Information will be kept private. Cross-site request forgery attacks (CSRF or XSRF for short) are used to send malicious requests from an authenticated user to a web application. The attacker can’t see the responses to the forged requests, so CSRF attacks focus on state changes, not theft of data.
What are the consequences of a CSRF attack?
The attacker can’t see the responses to the forged requests, so CSRF attacks focus on state changes, not theft of data. Successful CSRF attacks can have serious consequences, so let’s see how CSRF works and how you can prevent it.
