CVE-2025-27615
📋 TL;DR
The umatiGateway software exposes its web interface publicly by default in Docker deployments, allowing unauthorized users to view and modify configuration settings. This affects all users running umatiGateway with the default docker-compose configuration. The vulnerability stems from improper network binding that makes the admin interface accessible beyond localhost.

⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full control over umatiGateway configuration, potentially modifying OPC UA to MQTT mappings, injecting malicious messages, or disrupting industrial communication systems.
Likely Case
Unauthorized users access sensitive configuration data and make unauthorized changes to gateway settings, potentially causing operational disruptions.
If Mitigated
Limited to local network access only, requiring attacker to have internal network access to exploit.
🎯 Exploit Status
Exploitation requires only web browser access to port 8080
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 5d81a3412bc0051754a3095d89a06d6d743f2b16
Vendor Advisory: https://github.com/umati/umatiGateway/security/advisories/GHSA-qf9w-x9qx-2mq7
Restart Required: Yes
Instructions:
1. Update docker-compose.yml to use '127.0.0.1:8080:8080' instead of '8080:8080' 2. Pull latest umatiGateway image 3. Restart containers
🔧 Temporary Workarounds
Firewall Port Blocking
linuxBlock external access to port 8080 using host firewall
sudo ufw deny 8080
sudo firewall-cmd --permanent --remove-port=8080/tcp
sudo firewall-cmd --reload
Docker Network Restriction
allConfigure Docker to bind only to localhost
Edit docker-compose.yml: change 'ports: - "8080:8080"' to 'ports: - "127.0.0.1:8080:8080"'
🧯 If You Can't Patch
- Implement network segmentation to isolate umatiGateway from untrusted networks
- Deploy reverse proxy with authentication in front of umatiGateway interface
🔍 How to Verify
Check if Vulnerable:
Check if port 8080 is bound to 0.0.0.0 instead of 127.0.0.1: 'docker ps --format "table {{.Names}}\t{{.Ports}}"'Check Version:
docker inspect umatiGateway | grep -i commitVerify Fix Applied:
Verify port binding: 'netstat -tlnp | grep 8080' should show 127.0.0.1:8080, not 0.0.0.0:8080📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /admin paths
- Configuration change logs from unexpected IPs
Network Indicators:
- External connections to port 8080
- HTTP requests to umatiGateway admin interface from non-local IPs
SIEM Query:
