此次共审计3个漏洞

1. 前台SSRF漏洞

位于 /Application/Home/Controller/LoginController.class.php 控制器的otcurl方法存在curl_exec函数，且传参均可控，导致漏洞产生.

//须弥大呲花 2018年4月28日16:40:38public function otcurl($url,$params=false,$ispost=0){ $httpInfo = array(); $ch = curl_init(); curl_setopt( $ch, CURLOPT_HTTP_VERSION , CURL_HTTP_VERSION_1_1 ); curl_setopt( $ch, CURLOPT_USERAGENT , 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22' ); curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT , 30 ); curl_setopt( $ch, CURLOPT_TIMEOUT , 30); curl_setopt( $ch, CURLOPT_RETURNTRANSFER , true ); if( $ispost ) { curl_setopt( $ch , CURLOPT_POST , true ); curl_setopt( $ch , CURLOPT_POSTFIELDS , $params ); curl_setopt( $ch , CURLOPT_URL , $url ); } else { if($params){ curl_setopt( $ch , CURLOPT_URL , $url.'?'.$params ); }else{ curl_setopt( $ch , CURLOPT_URL , $url); } } $response = curl_exec( $ch ); if ($response === FALSE) { //echo "cURL Error: " . curl_error($ch); return false; } $httpCode = curl_getinfo( $ch , CURLINFO_HTTP_CODE ); $httpInfo = array_merge( $httpInfo , curl_getinfo( $ch ) ); curl_close( $ch ); return $response;}

Payload:

前台SSRF漏洞

2. 前台任意文件上传漏洞，无需登录

位于 /Common/Common/function.php 中有一处文件上传的操作，且未有任何过滤。函数代码如下：

function upload_file($files,$type){ $name = array_keys($files); $name = $name[0]; $ext = extend($files[$name]['name']); $img_url = "./Uploads/txt/".date('Y-m-d',time()).'/'; if (!file_exists($img_url)) { mkdir($img_url,0777,true); //echo $img_url; die; } $image_name = time().rand(100,999).".".$ext;//图片名字 $tmp = $files[$name]['tmp_name'];//临时名字 if(move_uploaded_file($tmp,$img_url.$image_name)){ $arr['re']=ltrim($img_url.$image_name,'.'); $arr['code']=200; return $arr; // return ltrim($img_url.$image_name,'.'); }else{ return 'error'; } }

追踪到 /Application/Home/Controller/LoginController.class.php 控制器的shangchuan方法调用了该函数，导致漏洞产生

//须弥大呲花 2018年6月19日11:23:19 上传public function shangchuan(){ // var_dump($_FILES);exit; echo json_encode(upload_file($_FILES,'image'));}

Payload:

3. 前台SQL注入，需要前台用户登录权限

位于 /Home/Controller/MemberController.class.php 控制器中的 my_up_level 方法通过$_GET传入变量$phone 并直接拼接进SQL语句，导致注入产生.

/* * 闯关记录* 2019年3月5日11:33:20 author:CL*/public function my_up_level(){ $prefix = C('DB_PREFIX'); //获取数据库前缀 $where = "ul.member_id='".session('member_id')."'"; if($_GET['phone']!='') $where .= " and (l.member_phone='".$_GET['phone']."' or l.member_name='".$_GET['phone']."')"; $this->assign('get', $_GET); $field = "ul.*,from_unixtime(ul.add_time,'%Y.%m.%d %H:%i:%s') as add_time,from_unixtime(ul.qr_time,'%Y.%m.%d %H:%i:%s') as qr_time,from_unixtime(ul.su_time,'%Y.%m.%d %H:%i:%s') as su_time ,le.level_title,l.member_name as qr_name,l.member_phone as qr_phone,l.member_img as qr_img,l.wx_name as qr_wx,l.zfb_name as qr_zfb"; // 全部 $all = M('member_up_level')->alias('ul')->join(array("left join ".$prefix."member_list l on l.member_id=ul.qr_id","left join ".$prefix."member_level le on le.id=ul.level"))->where($where)->field($field)->order("ul.id desc")->select(); if(!empty($all)){ foreach($all as $k=>$v){ if ($v['check_status'] == 2) { $v['state_title'] = '已确认'; } elseif ($v['check_status'] == 1) { $v['state_title'] = '未确认'; } elseif ($v['check_status'] == 3){ $v['state_title'] = '已拒绝'; } $all[$k] = $v; } } $this->assign('all',$all); $this->assign('all_num',count($all)); // 待审核 $dsh = M('member_up_level')->alias('ul')->join(array("left join ".$prefix."member_list l on l.member_id=ul.qr_id","left join ".$prefix."member_level le on le.id=ul.level"))->where($where." and ul.state='1'")->field($field)->order("ul.id desc")->select(); $this->assign('dsh',$dsh); $this->assign('dsh_num',count($dsh)); // 审核成功 $shcg = M('member_up_level')->alias('ul')->join(array("left join ".$prefix."member_list l on l.member_id=ul.qr_id","left join ".$prefix."member_level le on le.id=ul.level"))->where($where." and ul.state='2'")->field($field)->order("ul.id desc")->select(); $this->assign('shcg',$shcg); $this->assign('shcg_num',count($shcg)); // 审核失败 $shsb = M('member_up_level')->alias('ul')->join(array("left join ".$prefix."member_list l on l.member_id=ul.qr_id","left join ".$prefix."member_level le on le.id=ul.level"))->where($where." and ul.state='3'")->field($field)->order("ul.id desc")->select(); $this->assign('shsb',$shsb); $this->assign('shsb_num',count($shsb)); $this->display(); }

打个单引号直接就报错了，这里肯定有注入的
