Is this vulnerability remotely exploitable?

Yes, in typical deployments the module upload endpoint is reachable over HTTP(S). However, exploitation generally requires the ability to reach and use the module update functionality, which may be restricted to authenticated administrative users.

What level of access does an attacker need?

An attacker must be able to submit files to the module update handler. In many setups this is limited to authenticated users with module or system administration rights, but misconfigurations or shared credentials can broaden exposure.

What is the safest general fix pattern?

Implement a strict allowlist of permitted module package types, validate archive contents before accepting an upload, and store all uploaded content in non-executable locations while ensuring the web server cannot directly execute or interpret uploaded files.
