简要描述:

N久了,你们是修还是不修啊?这么蛋疼的一个漏洞.

详细说明:

先看admin_logs.php代码

code 区域

}







没有做任何过滤转义



但是管理员日志正常用户是没有办法直接控制的,我们就需要想办法间接去控制他



继续翻找代码 找关键字admin_log 找到有哪写代码会往日志数据库写数据的



找到user_msg.php文件有处 而这个是用来审核用户留言的 也就是说可控



code 区域
elseif ($_REQUEST['act'] == 'remove')
{
$msg_id = intval($_REQUEST['id']);

/* 检查权限 */
check_authz_json('feedback_priv');

$msg_title = $exc->get_name($msg_id);
$img = $exc->get_name($msg_id, 'message_img');
if ($exc->drop($msg_id))
{
/* 删除图片 */
if (!empty($img))
{
@unlink(ROOT_PATH. DATA_DIR . '/feedbackimg/'.$img);
}
$sql = "DELETE FROM " . $ecs->table('feedback') . " WHERE parent_id = '$msg_id' LIMIT 1";
$db->query($sql, 'SILENT');

admin_log(addslashes($msg_title), 'remove', 'message');
$url = 'user_msg.php?act=query&' . str_replace('act=remove', '', $_SERVER['QUERY_STRING']);
ecs_header("Location: $url\n");
exit;
}
else
{
make_json_error($GLOBALS['db']->error());
}
}









发现这里直接把 $msg_title写进了admin_log

code 区域
admin_log(addslashes($msg_title), 'remove', 'message');







$msg_title 是留言的标题 那在找留言出代码



code 区域
$action  = isset($_REQUEST['act']) ? trim($_REQUEST['act']) : 'default';
if ($action == 'act_add_message')
{
include_once(ROOT_PATH . 'includes/lib_clips.php');

/* 验证码防止灌水刷屏 */
if ((intval($_CFG['captcha']) & CAPTCHA_MESSAGE) && gd_version() > 0)
{
include_once('includes/cls_captcha.php');
$validator = new captcha();
if (!$validator->check_word($_POST['captcha']))
{
show_message($_LANG['invalid_captcha']);
}
}
else
{
/* 没有验证码时,用时间来限制机器人发帖或恶意发评论 */
if (!isset($_SESSION['send_time']))
{
$_SESSION['send_time'] = 0;
}

$cur_time = gmtime();
if (($cur_time - $_SESSION['send_time']) < 30) // 小于30秒禁止发评论
{
show_message($_LANG['cmt_spam_warning']);
}
}
$user_name = '';
if (empty($_POST['anonymous']) && !empty($_SESSION['user_name']))
{
$user_name = $_SESSION['user_name'];
}
elseif (!empty($_POST['anonymous']) && !isset($_POST['user_name']))
{
$user_name = $_LANG['anonymous'];
}
elseif (empty($_POST['user_name']))
{
$user_name = $_LANG['anonymous'];
}
else
{
$user_name = htmlspecialchars(trim($_POST['user_name']));
}

$user_id = !empty($_SESSION['user_id']) ? $_SESSION['user_id'] : 0;
$message = array(
'user_id' => $user_id,
'user_name' => $user_name,
'user_email' => isset($_POST['user_email']) ? htmlspecialchars(trim($_POST['user_email'])) : '',
'msg_type' => isset($_POST['msg_type']) ? intval($_POST['msg_type']) : 0,
'msg_title' => isset($_POST['msg_title']) ? trim($_POST['msg_title']) : '',
'msg_content' => isset($_POST['msg_content']) ? trim($_POST['msg_content']) : '',
'order_id' => 0,
'msg_area' => 1,
'upload' => array()
);







也没有对代码进行过滤 msg_title也是直接写入





漏洞证明:

那直接试试

code 区域
<script>alert(document.cookie)</script>





1.jpg





提交xss

2.jpg



成功



现在看后台

3.jpg



这里进行转义过滤 所以并没有形成xss



我们再删除这段留言后

进入日志查看



4.jpg





果然弹了

修复方案:

你们懂的
