Description
Map-OS 5.0.0 to before 5.2.2 contains a privilege escalation vulnerability in the REST users API that allows non-administrator operators holding the cUsuario permission to bypass permission-delegation and super-administrator protections. Attackers can send POST, PUT, or DELETE requests to /api/v1/usuarios to assign the Administrador group, reset the super administrator password, or delete higher-privileged users.
