Is this vulnerability remotely exploitable?

Yes, it can be remotely exploitable if the ZIP upload functionality is exposed over the network and accessible to an attacker (with or without authentication, depending on how the instance is configured).

Does an attacker need special privileges to exploit this?

The attacker must be able to access the problem import feature that accepts ZIP uploads. In many deployments this may require authentication with a teacher, administrator, or contest organizer role, but in misconfigured setups it could be exposed more broadly.

What is the safest general fix pattern for this issue?

The most robust fix is to strictly validate and canonicalize archive entry paths before extraction, ensure they cannot escape a designated directory, and extract only into non-web-exposed locations. Any entry that resolves outside the intended directory or uses suspicious path constructs should be rejected.
