This paper analyzes the ZTE Config Utility (ZCU), a configuration tool used for provisioning and managing ZTE network devices. It covers functionality, architecture, common use cases, security concerns, attack surface, and mitigation recommendations. The goal is to inform network operators, security engineers, and researchers about risks and best practices.
