Is this vulnerability remotely exploitable over the network?

Yes, it can be exploited remotely, but only by actors who can authenticate to AWS Research and Engineering Studio and access the FileBrowser functionality.

What level of access does an attacker need to exploit this?

The attacker needs valid credentials or a session that allows interaction with the FileBrowser API or UI. Anonymous, unauthenticated access is not sufficient under normal configurations.

What is the safest general fix pattern for this issue?

The safest approach is to eliminate shell-based command execution in FileBrowser logic, using language-native filesystem operations instead, and strictly validating all user-supplied input against well-defined, allowlisted expectations.
