CVSS: 8.6EPSS: 0%CPEs: 18EXPL: 0CVE-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 •

An attacker could send a crafted HTTP/HTTPS request to render the web server unavailable and/or lead to remote code execution caused by a stack-based buffer overflow vulnerability. A cold restart is required for recovering CompactLogix 5370 L1, L2, and L3 Controllers, Compact GuardLogix 5370 controllers, and Armor Compact GuardLogix 5370 Controllers Versions 20 - 30 and earlier. Un atacante podría enviar una petición HTTP/HTTPS creada para hacer que el servidor web no esté disponible y/o provocar una ejecución remota de código causada por una vulnerabilidad de desbordamiento de búfer basada en la región stack de memoria. Un reinicio en frío es requerido para recuperar los controladores CompactLogix 5370 L1, L2 y L3, los controladores Compact GuardLogix 5370 y los controladores Armor Compact GuardLogix 5370 versiones 20 a 30.014 y sistemas anteriores. • http://www.securityfocus.com/bid/108118 https://ics-cert.us-cert.gov/advisories/ICSA-19-120-01 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/1075979 • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
