Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation."

Los atacantes pueden explotar la configuración del analizador XML en system/import/xml.php para inyectar referencias de entidad file: // o php://filter que se resuelven y persisten en la base de datos de la aplicación, lo que permite la divulgación arbitraria de archivos y la sobrescritura de hashes de contraseñas de administrador para la escalada de privilegios."
