Is this vulnerability remotely exploitable over the internet?

It can be, if the Explorance Blue web service is exposed to the internet and an attacker can obtain or compromise valid credentials. The core requirement is authenticated access to the vulnerable file-handling endpoint, regardless of network location.

Does an attacker need elevated permissions to exploit this issue?

Not necessarily. Exploitation typically requires only the level of access needed to reach the vulnerable web service functionality. Even relatively low-privileged authenticated accounts may be sufficient if they can interact with the affected file operations.

What is the safest general fix pattern for this kind of flaw?

The most robust approach is to strictly lock down file-handling behavior: - Restrict file types and enforce content-based validation where feasible. - Limit all file operations to dedicated, non-executable storage locations. - Remove or refactor any logic that allows user input to control which files are accessed in sensitive directories. These patterns reduce the chance that any user-influenced file can become executable.
