Is this vulnerability remotely exploitable?

Yes, but it requires authenticated access to an administrator account or equivalent privileges that can access the theme import functionality. Once authenticated, the attacker can exploit the issue over the network.

What level of access is needed to exploit this?

Exploitation typically requires administrator-level access to the Open eClass web interface. Attackers may obtain this access through credential theft, weak passwords, or other application vulnerabilities.

What is the safest general fix pattern for this issue?

The most robust pattern is to strictly validate and restrict uploaded content: allow only specific non-executable file types in theme archives, normalize and constrain extraction paths, and ensure uploads are stored in non-executable directories where the web server cannot run them as code.
