High (7.0). EPSS 0.8% estimated probability of exploitation activity in the next 30 days.
Nexbox A95X TV boxes built on the Amlogic S905X platform contain an unauthenticated console exposed via an internal UART header on the PCB that allows physical attackers to obtain an interactive shell as uid 2000 (system) without any credentials. Attackers with physical access and a USB-to-TTL adapter can leverage this shell to reach the pppoe_wrapper vendor daemon, which contains an OS command injection vulnerability executed as root, resulting in full root-level compromise of the device.
