CVE-2024-54017
CVE-2024-54017
En resumen
Los dispositivos de protección SIPROTEC 5 utilizan generación débil de números aleatorios en funciones de seguridad, permitiendo que atacantes predigan o falsifiquen credenciales. Esto afecta la integridad y confidencialidad de comunicaciones en infraestructuras críticas del sistema eléctrico.
Detalle técnico
La vulnerabilidad proviene de entropía insuficiente en la generación de números aleatorios (CWE-334) implementada en múltiples modelos y versiones de firmware del SIPROTEC 5. Un atacante con acceso a la red del dispositivo puede potencialmente predecir valores criptográficos o falsificar tokens de autenticación, comprometiendo la confidencialidad e integridad de las comunicaciones de gestión.
