CWE-306Missing Authentication for Critical Functionality CWE-670Always-Incorrect Control Flow Implementation

Description

An endpoint used during initial appliance setup did not require authentication and did not correctly enforce its intended state precondition, so during the initial activation window an unauthenticated network attacker could repeatedly re-trigger the privileged activation process. This could disrupt setup and leave the appliance in an incompletely configured state. The issue is only reachable while an appliance is being activated for the first time and not yet fully configured.
