## Description

Ratta SuperNote A6 X2 Nomad before December 2024 allows remote code execution because an arbitrary firmware image (signed with debug keys) can be sent to TCP port 60002, and placed into the correct image-update location as a consequence of both directory traversal and unintended handling of concurrency.
