Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

Requiring explicit authorization for each internal connection prevents missing authorization.
Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly.
Manages privileges by authorizing only approved personnel and supervising those lacking required authorizations for maintenance.
