CVE-2026-27843

A vulnerability exists in SenseLive X3050's web management interface that allows critical configuration parameters to be modified without sufficient authentication or server-side validation. By applying unsupported or disruptive values to recovery mechanisms and network settings, an attacker can induce a persistent lockout state. Because the device lacks a physical reset button, recovery requires specialized technical access via the console to perform a factory reset, resulting in a total denial-of-service for the gateway and its connected RS-485 downstream systems.

Summary		(es) Una vulnerabilidad existe en la interfaz de gestión web de SenseLive X3050 que permite modificar parámetros de configuración críticos sin autenticación suficiente o validación del lado del servidor. Al aplicar valores no soportados o disruptivos a los mecanismos de recuperación y a la configuración de red, un atacante puede inducir un estado de bloqueo persistente. Debido a que el dispositivo carece de un botón de reinicio físico, la recuperación requiere acceso técnico especializado a través de la consola para realizar un restablecimiento de fábrica, lo que resulta en una denegación de servicio total para la pasarela y sus sistemas descendentes RS-485 conectados.
