Technical details
The vulnerability is a missing authentication flaw (CWE-306) in the /sbin/mtk_dut binary, which is exposed on TCP port 9000. This service is intended for debugging but lacks any access control, allowing an unauthenticated attacker on the local area network (LAN) or adjacent network to interact with the interface. By sending arbitrary UCC commands to this port, an attacker can achieve remote code execution with the privileges of the service. The issue is resolved in firmware version W6x_GBL_2.00.000008 and later.
