Descriptions

A vulnerability has been identified in SIMATIC CP 1604 (All versions), SIMATIC CP 1616 (All versions), SIMATIC CP 1623 (All versions), SIMATIC CP 1626 (All versions), SIMATIC CP 1628 (All versions). Affected devices insufficiently control continuous mapping of direct memory access (DMA) requests. This could allow local attackers with administrative privileges to cause a denial of service situation on the host. A physical power cycle is required to get the system working again.

Se ha identificado una vulnerabilidad en:
SIMATIC CP 1604 (Todas las versiones),
SIMATIC CP 1616 (Todas las versiones),
SIMATIC CP 1623 (Todas las versiones),
SIMATIC CP 1626 (Todas las versiones),
SIMATIC CP 1628 (Todas las versiones).
Los dispositivos afectados controlan insuficientemente el mapeo continuo de las solicitudes de acceso directo a la memoria (DMA). Esto podría permitir que atacantes locales con privilegios administrativos provoquen una situación de denegación de servicio en el host. Se requiere un ciclo de energía físico para que el sistema vuelva a funcionar.
