CSRF, and the cookie flag
The article discusses Cross-Site Request Forgery (CSRF) and its implications for web security. It explains how CSRF exploits the way browsers handle cookies, allowing unauthorized actions without user interaction. The article also outlines defenses against CSRF, including CSRF tokens and SameSite cookies.
- ▪CSRF is a web security vulnerability that allows attackers to perform actions on behalf of authenticated users without their consent.
- ▪The browser automatically attaches cookies to requests based on the destination domain, which can be exploited by malicious sites.
- ▪CORS does not prevent CSRF attacks because it only controls what JavaScript can read from cross-origin responses, not whether requests are sent.
