CVE-2023-44319
CVE-2023-44319
En resumen
Estos dispositivos de red industrial utilizan algoritmos de cifrado débil para proteger las comunicaciones, permitiendo que atacantes intercepten o descifren datos sensibles. Afecta routers y puertas de enlace usados en infraestructura crítica, permitiendo potencialmente acceso no autorizado a sistemas industriales.
Detalle técnico
La vulnerabilidad identifica el uso de algoritmos criptográficos insuficientemente fuertes en dispositivos Siemens RUGGEDCOM y SCALANCE (versiones de firmware anteriores a V8.0 y V3.0.0). Un atacante con acceso a la red puede interceptar comunicaciones cifradas y recuperar potencialmente datos en texto plano debido a implementaciones débiles de cifrado; requiere proximidad al tráfico de red pero no requiere autenticación.

Affected devices use a weak checksum algorithm to protect the configuration backup that an administrator can export from the device. This could allow an authenticated attacker with administrative privileges or an attacker that tricks a legitimate administrator to upload a modified configuration file to change the configuration of an affected device.
