Nie byłbym sobą, gdybym nie sprawdził, czy moja praca faktycznie działa, dlatego musiałem sprawdzić mój blog przy pomocy programu wpscan. Wystartowałem maszynę wirtualną z zainstalowanym systemem Kali Linux i uruchomiłem konsolę:

Na początku nieźle, a teraz pora na sprawdzenie podatności.

Zatem WordPress nie posiada poddatności w zainstalowanych wtyczkach, nie ma również możliwości enumeracji użytkowników. Pozostaje jedynie poprawić ukrycie wersji WordPressa. Znalazłem taki kod na stronie, który trzeba dodać do pliku functions.php
// remove version from head
remove_action('wp_head', 'wp_generator');
// remove version from rss
add_filter('the_generator', '__return_empty_string');
// remove version from scripts and styles
function remove_version_scripts_styles($src) {
if (strpos($src, 'ver=')) {
$src = remove_query_arg('ver', $src);
}
return $src;
}
add_filter('style_loader_src', 'remove_version_scripts_styles', 9999);
add_filter('script_loader_src', 'remove_version_scripts_styles', 9999);
To pora na ostateczny test.

Niestety nadal nie mogę ukryć wersji WordPressa, skaner rozpoznaje wersję na podstawie pliku css, który posiada unikalny odcisk palca.

Podsumowanie:
Strona nie posiada żadnych znanych podatności, posiada ukryty panel logowania, nie można enumerować użytkowników, pozostaje wyłącznie problem z wersją systemu CMS. Można to odkryć stosując najnowszą wersję skanera wpscan. Ogónie oceniam wynik na ocenę bardzo dobry z minusem (wersja CMS). Pocieszam się, że wraz z nowszą wersją WordPressa uda mi się rozwiązać ten problem. To wszystko w sprawie tej strony.
