Организационные меры:
Компания «Сименс» определила следующие конкретные обходные пути и меры по смягчению последствий данной уязвимости:
Для SCALANCE M800, SCALANCE S615 и RUGGEDCOM RM1224: Отключите DNS-прокси в конфигурации устройства (Система - DNS - DNS-прокси - Отключить флажок «Включить DNS-прокси») и настройте подключенные устройства во внутренней сети для использования другого DNS-сервера.
Для SCALANCE W1750D: Если функциональность «OpenDNS», «Captive Portal» или «URL redirection» не используется,
разверните правила брандмауэра в конфигурации устройства, чтобы заблокировать входящий доступ к порту 53/UDP.
