Descriptions

Honeywell Experion PKS Safety Manager through 2022-05-06 has Missing Authentication for a Critical Function. According to FSCT-2022-0051, there is a Honeywell Experion PKS Safety Manager multiple proprietary protocols with unauthenticated functionality issue. The affected components are characterized as: Honeywell Experion TCP (51000/TCP), Safety Builder (51010/TCP). The potential impact is: Manipulate controller state, Manipulate controller configuration, Manipulate controller logic, Manipulate controller files, Manipulate IO. The Honeywell Experion PKS Distributed Control System (DCS) Safety Manager utilizes several proprietary protocols for a wide variety of functionality, including process data acquisition, controller steering and configuration management. These protocols include: Experion TCP (51000/TCP) and Safety Builder (51010/TCP). None of these protocols have any authentication features, allowing any attacker capable of communicating with the ports in question to invoke (a subset of) desired functionality. There is no authentication functionality on the protocols in question. An attacker capable of invoking the protocols' functionalities could achieve a wide range of adverse impacts, including (but not limited to), the following: for Experion TCP (51000/TCP): Issue IO manipulation commands, Issue file read/write commands; and for Safety Builder (51010/TCP): Issue controller start/stop commands, Issue logic download/upload commands, Issue file read commands, Issue system time change commands. A mitigating factor with regards to some, but not all, of the above functionality is that these require the Safety Manager physical keyswitch to be in the right position.

Honeywell Experion PKS Safety Manager versiones hasta 06-05-2022, presenta una Falta de Autenticación para una Función Crítica. De acuerdo con FSCT-2022-0051, se presenta un problema de protocolos propietarios múltiples de Honeywell Experion PKS Safety Manager con funcionalidad no autenticada. Los componentes afectados son caracterizados como: Honeywell Experion TCP (51000/TCP), Safety Builder (51010/TCP). El impacto potencial es: Manipular el estado del controlador, Manipular la configuración del controlador, Manipular la lógica del controlador, Manipular los archivos del controlador, Manipular la IO. El administrador de seguridad del sistema de control distribuido (DCS) Experion PKS de Honeywell usa varios protocolos propios para una amplia variedad de funciones, como la adquisición de datos de proceso, la dirección del controlador y la administración de la configuración. Estos protocolos incluyen Experion TCP (51000/TCP) y Safety Builder (51010/TCP). Ninguno de estos protocolos presenta funciones de autenticación, lo que permite a cualquier atacante capaz de comunicarse con los puertos en cuestión invocar (un subconjunto de) la funcionalidad deseada. No se presenta ninguna funcionalidad de autenticación en los protocolos en cuestión. Un atacante capaz de invocar las funcionalidades de los protocolos podría lograr una amplia gama de impactos adversos, incluyendo (pero no limitados a), lo siguiente: para Experion TCP (51000/TCP): Emitir comandos de manipulación IO, Emitir comandos de lectura/escritura de archivos; y para Safety Builder (51010/TCP): Emitir comandos de arranque/parada de controlador, Emitir comandos de descarga/carga de lógica, Emitir comandos de lectura de archivos, Emitir comandos de cambio de hora del sistema. Un factor atenuante con respecto a algunas de las funciones anteriores, pero no todas, es que éstas requieren que el interruptor de llave físico del Safety Manager esté en la posición correcta
