Is this vulnerability remotely exploitable?

Yes. If the FileThingie interface is reachable over the network and upload permissions are obtainable, an attacker can exploit the issue remotely by uploading a crafted ZIP and invoking the unzip functionality.

What level of access does an attacker need?

The attacker needs the ability to upload ZIP archives through `ft2.php`. In some deployments this may require valid credentials, but in others misconfigured or shared access can make it effectively public.

What is the safest general fix pattern?

The most robust pattern is to prevent any executable content from being uploaded or extracted into web-accessible locations. Enforce strict allowlists on file types, isolate uploads to non-executable directories, and ensure archive extraction cannot place files outside controlled paths.
