CVE-2026-119740 · Severity: medium · CVSS 6.8 · Published 2026-11-02

The Nexbox A95X Android TV box exposes an unauthenticated serial console via a physical UART header that grants shell access without credentials. An attacker with physical access can use this access to reach the root-level pppoe_wrapper daemon, which is vulnerable to command injection, allowing complete compromise of the device.

## Technical details

The vulnerability chains two issues: (1) an unauthenticated UART console (CWE-306) on the PCB header offering a shell as uid 2000 with no password, and (2) a CWE-78 OS command injection in the pppoe_wrapper root daemon that binds an AF_UNIX datagram socket with mode 777 and directly passes user-supplied command arguments to system() without validation. An attacker with physical access and a USB-to-TTL adapter can reach the pppoe_wrapper socket and inject arbitrary commands executed as root.
