Full vulnerability record from the local CVENow database.

Description

ChurchCRM is an open-source church management system. Prior to 7.3.2, UserEditor.php processes user account creation and permission updates entirely through $_POST parameters with no CSRF token validation. An unauthenticated attacker can craft a malicious HTML page that, when visited by an authenticated administrator, silently elevates any low-privilege user to full administrator or creates a new admin backdoor account without the victim's knowledge This vulnerability is fixed in 7.3.2.

Un atacante no autenticado puede elaborar una página HTML maliciosa que, al ser visitada por un administrador autenticado, eleva silenciosamente a cualquier usuario de bajo privilegio a administrador completo o crea una nueva cuenta de puerta trasera de administrador sin el conocimiento de la víctima. Esta vulnerabilidad está corregida en 7.3.2."
