漏洞文件为 `showFile.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'];
|
|
$file_path = '../../../log/'.$file_name;
|
|
$fp = fopen($file_path, "r");
|
|
while($line = fgets($fp)){
|
|
$line = nl2br(htmlentities($line, ENT_COMPAT, "utf-8"));
|
|
echo '<span style="font-size:16px">'.$line.'</span>';
|
|
}
|
|
fclose($fp);
|
|
?>
|
|
```
