Is this vulnerability remotely exploitable beyond the local network?

Yes, if the Catalyst management interface or API is reachable over the network and an attacker can obtain or abuse credentials with template permissions, they can achieve root-level code execution on cluster nodes from remote locations.

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

The attacker needs access to an account or integration that has `template.create` or `template.update` permissions. No direct shell or node access is required; the platform will execute the malicious commands during server provisioning.

What is the safest general fix pattern for this class of vulnerability?

The most robust fix is to eliminate direct, unsandboxed execution of user-defined shell commands on the host. Run install logic in isolated environments under non-root identities, and replace free-form scripting with constrained, well-defined operations wherever possible.
