Is this vulnerability remotely exploitable over the internet?

Yes, if the BeyondTrust RS or PRA instance is reachable over the network (including the internet) on the vulnerable interface, an attacker can exploit it remotely without prior authentication.

Does an attacker need valid credentials or user accounts?

No. This is a pre-authentication issue, so the attacker does not need credentials or an existing account; they only need network access to the affected service.

What is the safest general fix pattern for developers?

The safest pattern is to remove all string-based shell or OS command construction from request-handling code, especially before authentication, and to use high-level, parameterized APIs that cannot interpret user input as executable commands. If system calls are necessary, arguments should be passed as structured parameters, not concatenated strings.
