      "value": "3X-UI is a web control panel for managing Xray-core servers. Prior to 3.3.1, an authenticated administrator can abuse the database import functionality to achieve arbitrary file write on the host by modifying Xray configuration values stored in the database. This can be leveraged to obtain code execution and persistent access as the user running Xray (including root when Xray is running as root). This vulnerability is fixed in 3.3.1."

      "value": "3X-UI es un panel de control web para gestionar servidores Xray-core. Antes de la 3.3.1, un administrador autenticado puede abusar de la funcionalidad de importación de la base de datos para lograr la escritura arbitraria de archivos en el host modificando los valores de configuración de Xray almacenados en la base de datos. Esto puede ser aprovechado para obtener la ejecución de código y acceso persistente como el usuario que ejecuta Xray (incluyendo root cuando Xray se ejecuta como root). Esta vulnerabilidad está corregida en la versión 3.3.1."
