FKIE_CVE-2025-68140

Vulnerability from fkie_nvd - Published: 2026-01-21 20:16 - Updated: 2026-02-06 21:22
Severity ?
4.3 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
EVerest is an EV charging software stack. Prior to version 2025.9.0, once the validity of the received V2G message has been verified, it is checked whether the submitted session ID matches the registered one. However, if no session has been registered, the default value is 0. Therefore, a message submitted with a session ID of 0 is accepted, as it matches the registered value. This could allow unauthorized and anonymous indirect emission of MQTT messages and communication with V2G messages handlers, updating a session context. Version 2025.9.0 fixes the issue.

      "value": "EVerest es una pila de software de carga de VE. Antes de la versi\u00f3n 2025.9.0, una vez verificada la validez del mensaje V2G recibido, se comprueba si el ID de sesi\u00f3n enviado coincide con el registrado. Sin embargo, si no se ha registrado ninguna sesi\u00f3n, el valor predeterminado es 0. Por lo tanto, un mensaje enviado con un ID de sesi\u00f3n de 0 es aceptado, ya que coincide con el valor registrado. Esto podr\u00eda permitir la emisi\u00f3n indirecta no autorizada y an\u00f3nima de mensajes MQTT y la comunicaci\u00f3n con los manejadores de mensajes V2G, actualizando un contexto de sesi\u00f3n. La versi\u00f3n 2025.9.0 corrige el problema."
