CVE-2019-18289
📋 TL;DR
A critical vulnerability in Siemens SPPA-T3000 MS3000 Migration Server allows remote attackers to cause denial-of-service or execute arbitrary code by sending specially crafted packets to TCP port 5010. This affects all versions of the MS3000 Migration Server component. Attackers need network access to the vulnerable server to exploit this vulnerability.

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with full system compromise, allowing attackers to take complete control of the MS3000 server and potentially pivot to other industrial control systems.
Likely Case
Denial-of-service condition disrupting migration operations and industrial control system functionality.
If Mitigated
No impact if proper network segmentation and access controls prevent attackers from reaching the vulnerable service.
🎯 Exploit Status
Exploitation requires sending specifically crafted packets to port 5010/tcp. Public proof-of-concept code exists in Packet Storm references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in available references - consult Siemens advisory for specific patched versions
Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-451445.pdf
Restart Required: Yes
Instructions:
1. Review Siemens Security Advisory SSA-451445. 2. Apply the recommended updates from Siemens. 3. Restart affected services/systems. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allBlock access to port 5010/tcp from untrusted networks
iptables -A INPUT -p tcp --dport 5010 -j DROP
netsh advfirewall firewall add rule name="Block MS3000 Port" dir=in action=block protocol=TCP localport=5010
Access Control Lists
linuxRestrict access to port 5010/tcp to only authorized management systems
iptables -A INPUT -p tcp --dport 5010 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 5010 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate MS3000 servers from untrusted networks
- Deploy intrusion detection/prevention systems to monitor and block malicious traffic to port 5010
🔍 How to Verify
Check if Vulnerable:
Check if MS3000 Migration Server is running and listening on port 5010/tcp: netstat -an | grep 5010 or ss -tlnp | grep 5010Check Version:
Consult Siemens SPPA-T3000 documentation for version checking commands specific to the MS3000 Migration Server componentVerify Fix Applied:
Verify patch installation through Siemens update verification tools and confirm port 5010 is no longer vulnerable to crafted packets📡 Detection & Monitoring
Log Indicators:
