齐博CMS 二次注入

漏洞作者： Power

shop/join.php中

if($action=="postnew") {  //自定义字段的合法检查与数据处理   $Module_db->checkpost($field_db,$postdb,'');//跟踪  join_post();     unset($id_array);

checkpost()函数中

function checkpost($field_db,&$postdb,$rsdb=''){  foreach($field_db AS $key=>$rs)  { .................省略   else   {    if(is_array($postdb[$key])){        $postdb[$key]='/#/'.implode("/#/",$postdb[$key]).'/#/';    }    //过滤不安全的字符    $postdb[$key]=filtrate($postdb[$key]);//对传递过来的数据进行过滤   }   if(strlen($postdb[$key])>30000){    showerr("内容不能大于1.5万个汉字");   }  } }

上面的我无法利用，但是在shop//member/address.php中

elseif($action=="postnew"){  $db->query("INSERT INTO `{$_pre}address` (`uid` ,`order_username` ,`order_phone` ,`order_mobphone` ,`order_email` ,`order_qq` ,`order_postcode` ,`order_address` ) VALUES ('$lfjuid', '$order_username', '$order_phone', '$order_mobphone', '$order_email', '$order_qq', '$order_postcode', '$order_address')");//直接转义之后入库  refreshto("?job=list",'',0); }elseif($action=="edit"){  checkrid($rid);  $db->query("UPDATE `{$_pre}address` SET order_username='$order_username',order_phone='$order_phone',order_email='$order_email',order_qq='$order_qq',order_postcode='$order_postcode',order_address='$order_address',order_mobphone='$order_mobphone' WHERE rid='$rid'");//转移后入库  refreshto("?job=list",'',0); }

在shop/join.php中

if($action=="postnew") {  //自定义字段的合法检查与数据处理   $Module_db->checkpost($field_db,$postdb,'');  join_post();//跟踪

join_post()函数中

function join_post(){  extract($GLOBALS);  global $postdb,$listdb;  if(!table_field("{$_pre}join",'products')){   $db->query("ALTER TABLE `{$_pre}join` ADD `products` TEXT NOT NULL ;");  }  $query = $db->query("SELECT * FROM {$_pre}content WHERE id IN (".implode(',',$_ar).")");  while($rs = $db->fetch_array($query)){   $rs[price] = str_replace(',','',$rs[price]);   $listdb[$rs[uid]][] = $rs; /*   var_dump($listdb);   exit; */  }   if($postdb[address_type]>0){   $ts = $db->get_one("SELECT * FROM `{$_pre}address` WHERE uid='$lfjuid' AND rid='$postdb[address_type]'");     //数据出库   $postdb[order_username] = $ts[order_username];   $postdb[order_phone] = $ts[order_phone];   $postdb[order_mobphone] = $ts[order_mobphone];   $postdb[order_email] = $ts[order_email];   $postdb[order_qq] = $ts[order_qq];   $postdb[order_postcode] = $ts[order_postcode];   $postdb[order_address] = $ts[order_address];  }elseif($postdb[address_type]=='-1'){    $db->query("INSERT INTO `{$_pre}address` ( `uid` , `order_username` , `order_phone` , `order_mobphone` , `order_email` , `order_qq` , `order_postcode` , `order_address` ) VALUES ('$lfjuid' , '$postdb[order_username]' , '$postdb[order_phone]' , '$postdb[order_mobphone]' , '$postdb[order_email]' , '$postdb[order_qq]' , '$postdb[order_postcode]' , '$postdb[order_address]')");  } }

/shop/join.php中

if($action=="postnew") {  //自定义字段的合法检查与数据处理   $Module_db->checkpost($field_db,$postdb,'');         join_post();//此函数取出入库数据  unset($id_array);  foreach($listdb AS $uid=>$array){   $totalmoney = 0;   $detail='';   foreach($array AS $_rs){    $totalmoney+=$_rs[price]*$p_totalArray[$_rs[id]];    $detail[] = "$_rs[id]={$p_totalArray[$_rs[id]]}";   }   $products = addslashes( implode(',',$detail) );    $rs=$db->get_one("SELECT * FROM `{$pre}purse` WHERE uid='$uid'");   $parray=unserialize($rs[config]);    if($postdb[order_sendtype]==2){   //平邮    $totalmoney+=floatval($parray[slow_send]);   }elseif($postdb[order_sendtype]==3){ //快递    $totalmoney+=floatval($parray[norm_send]);   }elseif($postdb[order_sendtype]==4){ //EMS    $totalmoney+=floatval($parray[ems_send]);   }   //$totalmoney = number_format($totalmoney,2);   /*往主信息表插入内容*/   $db->query("INSERT INTO `{$_pre}join` ( `mid` , `cid` , `cuid` ,  `posttime` ,  `uid` , `username` , `yz` , `ip` ,  `totalmoney`,`products`)    VALUES (   '$mid' , '$_rs[id]' , '$uid', '$timestamp','$lfjdb[uid]','$lfjdb[username]','0','$onlineip','$totalmoney','$products')");   $id = $id_array[] = $db->insert_id();    unset($sqldb);   $sqldb[]="id='$id'";   $sqldb[]="uid='$lfjuid'";   /*检查判断辅信息表要插入哪些字段的内容*/   foreach( $field_db AS $key=>$value){    isset($postdb[$key]) && $sqldb[]="`{$key}`='{$postdb[$key]}'";   }   $sql=implode(",",$sqldb);   $db->query("INSERT INTO `{$_pre}content_$mid` SET $sql");//数据入库产生注入

漏洞证明：

估计是我的Mysql 注册版本太低，不能报错注入，http://www.tongyuxian.com/shop/此网站躺抢

首先注册一个个人用户，访问http://www.tongyuxian.com/shop//member/address.php?job=postnew

然后购买商品，结算，使用存在的地址。
