CVE-2020-6998 – Rockwell Automation CompactLogix 5370 and ControlLogix 5570 Controllers Improper Input Validation

https://notcve.org/view.php?id=CVE-2020-6998

The connection establishment algorithm found in Rockwell Automation CompactLogix 5370 and ControlLogix 5570 versions 33 and prior does not sufficiently manage its control flow during execution, creating an infinite loop. This may allow an attacker to send specially crafted CIP packet requests to a controller, which may cause denial-of-service conditions in communications with other products. El algoritmo de establecimiento de conexión encontrado en Rockwell Automation CompactLogix 5370 and ControlLogix 5570 versiones 33 y anteriores, no administra suficientemente su flujo de control durante la ejecución, creando un bucle infinito. Esto puede permitir a un atacante enviar peticiones de paquetes CIP especialmente diseñados a un controlador, lo que puede causar condiciones de denegación de servicio en las comunicaciones con otros productos • https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/1130398 https://www.cisa.gov/uscert/ics/advisories/icsa-21-061-02 • CWE-20: Improper Input Validation •
