Dräger SC Monitoring devices (SC 6002XL, SC 6802XL, SC 7000, SC 8000, SC 9000 XL) contain a denial-of-service vulnerability in all software versions that allows unauthenticated attackers to reboot the monitor by sending a malformed network packet. Attackers can repeatedly send such malformed packets to disrupt patient monitoring until the device falls back to default configuration and loses network connectivity.
CVE-2019-25720 is a denial-of-service vulnerability affecting Dräger SC monitoring devices that allows unauthenticated attackers to remotely reboot critical patient monitoring equipment via malformed network packets. With no available patch and no authentication required, this vulnerability poses a significant risk to healthcare facilities in Saudi Arabia that rely on these devices for continuous patient monitoring. The lack of exploit availability provides limited immediate threat, but the potential for service disruption in clinical settings demands urgent mitigation.
Immediate Actions:
1. Inventory all Dräger SC monitoring devices (SC 6002XL, SC 6802XL, SC 7000, SC 8000, SC 9000 XL) in your healthcare facilities
2. Implement network segmentation to isolate patient monitoring devices on dedicated VLANs with restricted access
3. Deploy network access controls (NAC) to prevent unauthorized devices from connecting to monitoring networks
4. Enable logging and monitoring of all network traffic to/from affected devices
Compensating Controls:
5. Implement firewall rules to restrict network access to monitoring devices - allow only authorized clinical workstations and nursing stations
6. Disable unnecessary network services on monitoring devices if operationally feasible
7. Monitor device logs for unexpected reboot events and configure alerts
8. Establish manual backup monitoring procedures for critical patients during potential outages
9. Implement network-based intrusion detection signatures to identify malformed packets targeting these devices
10. Conduct regular device integrity checks and document baseline configurations
Detection Rules:
- Monitor for unexpected reboot events in device logs
- Alert on malformed or suspicious network packets destined to monitoring device ports
- Track device uptime anomalies and frequent restart patterns
- Monitor for unauthorized network access attempts to device management interfaces
الإجراءات الفورية:
1. قم بحصر جميع أجهزة مراقبة درايجر SC في منشآتك الصحية
2. تطبيق تقسيم الشبكة لعزل أجهزة المراقبة على شبكات افتراضية مخصصة
3. نشر عناصر التحكم في الوصول إلى الشبكة لمنع الأجهزة غير المصرح بها
4. تفعيل تسجيل ومراقبة جميع حركة المرور الشبكية
الضوابط البديلة:
5. تطبيق قواعد جدار الحماية لتقييد الوصول إلى أجهزة المراقبة
6. تعطيل الخدمات الشبكية غير الضرورية إن أمكن
7. مراقبة سجلات الجهاز للكشف عن أحداث إعادة التشغيل غير المتوقعة
8. وضع إجراءات مراقبة يدوية احتياطية للمرضى الحرجين
9. تطبيق توقيعات كشف التسلل لتحديد الحزم المعيبة
10. إجراء فحوصات منتظمة لسلامة الجهاز
