WP 3.2.1 [уязвимость]

Собственно сталкиваюсь уже второй раз за полторы недели. Пока что самой высокой версией WP, которую заметил инфицированной, является 3.2.1.

Уязвимость в инсталлере плагинов, который позволяет установить шелл под видом плагина из-за недостаточной фильтрации данных.

Сам шелл можно лицезреть здесь.

Симптомы:

• повышенная нагрузка (вплоть до DoS) с IP ботов мэйнлинка и линкфида.
• в /wp-content/plugins/ папки с шеллами имеют названия вида zxaiawuquya и zlfmjbpfmbc.
• в /wp-content/uploads/ те же шеллы, но в упакованном виде для инсталла.
• шелл имеет стандартное название gsm.php.
• ClamAV детектит шелл как Trojan.PHP.C99Shell. Шелл 2009 года в новой обёртке для WP.

Последствия:

• линкфид, мэйллинк и другие биржи ссылок.
• все .htaccess в пределах досягаемости содержат следующие перенаправления:

Не удалось понять подвержены ли уязвимости более свежие версии WP, потому как в описании http://codex.wordpress.org/Version_3.3 нет ничего похожего на исправление уязвимости с установкой плагина.

В первую очередь интересуют хостеры, которые находили у своих клиентов сие чудо. Также интересуют версии инфицированных доноров.
