Is this vulnerability remotely exploitable?

No, it is a local privilege escalation issue. An attacker must already have the ability to run commands on the affected system.

Does exploitation require administrative or special access?

Exploitation generally starts from a normal, non-privileged account. The weakness allows that account to gain higher privileges through the mismanaged re-execution behavior.

What is the safest general fix pattern for this type of bug?

Rigorously drop all elevated privileges before executing or re-executing any user-influenced commands, and design helpers so that their default and steady-state operation occurs under an unprivileged account.
