Descriptions

Honeywell Alerton Ascent Control Module (ACM) through 2022-05-04 allows unauthenticated configuration changes from remote users. This enables configuration data to be stored on the controller and then implemented. A user with malicious intent can send a crafted packet to change the controller configuration without the knowledge of other users, altering the controller's function capabilities. The changed configuration is not updated in the User Interface, which creates an inconsistency between the configuration display and the actual configuration on the controller. After the configuration change, remediation requires reverting to the correct configuration, requiring either physical or remote access depending on the configuration that was altered.

El módulo de control Alerton Ascent (ACM) de Honeywell versiones hasta 04-05-2022, permite realizar cambios de configuración no autenticados desde usuarios remotos. Esto permite que los datos de configuración sean almacenados en el controlador y luego son implementados. Un usuario con intenciones maliciosas puede enviar un paquete diseñado para cambiar la configuración del controlador sin el conocimiento de otros usuarios, alterando las capacidades de funcionamiento del controlador. La configuración modificada no es actualizada en la interfaz de usuario, lo que crea una incoherencia entre la visualización de la configuración y la configuración real en el controlador. Después del cambio de configuración, la remediación requiere revertir a la configuración correcta, requiriendo acceso físico o remoto dependiendo de la configuración que fue alterada
