, base64_decode()
, exec()
, or external links, may indicate malicious intent.ova-tools.php
Suppose ova-tools.php
processes user-supplied file paths but lacks input validation or sanitization. A hacker could try to exploit it by entering a crafted URL like:

// Sanitize and restrict file parameter
if (isset($_GET['file'])) {
$allowed_files = ['file1.txt', 'file2.txt']; // Specify allowable files
$file = basename($_GET['file']); // Prevent directory traversal
if (in_array($file, $allowed_files)) {
$filepath = '/path/to/files/' . $file;
if (file_exists($filepath)) {
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $file);
readfile($filepath);
exit;
} else {
wp_die('File not found.');
}
} else {
wp_die('Unauthorized file access.');
}
} else {
wp_die('No file specified.');
