Detailsinfo

A vulnerability classified as very critical has been found in Nexbox A95X (affected version not known). This affects some unknown functionality of the component pppoe_wrapper. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at mstreet97.github.io. This vulnerability is uniquely identified as CVE-2026-119740 since 10/30/2026. The exploitability is told to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.
