CVE-2025-30003
📋 TL;DR
This SQL injection vulnerability in TeleControl Server Basic allows authenticated remote attackers to bypass authorization controls, read/write to the database, and execute code with NetworkService permissions. It affects all versions before V3.1.2.2. Attackers need access to port 8000 on systems running vulnerable versions.
💻 Affected Systems
- TeleControl Server Basic
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with NetworkService privileges leading to lateral movement, data exfiltration, and persistent backdoor installation.
Likely Case
Database manipulation, credential theft, and unauthorized access to control systems data.
If Mitigated
Limited impact due to network segmentation and strict authentication controls preventing access to vulnerable port.
🎯 Exploit Status
Requires authenticated access but SQL injection is typically straightforward to exploit once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V3.1.2.2
Vendor Advisory: https://cert-portal.siemens.com/productcert/html/ssa-443402.html
Restart Required: Yes
Instructions:
1. Download V3.1.2.2 from Siemens portal. 2. Backup configuration and data. 3. Stop TeleControl Server Basic service. 4. Install update. 5. Restart service and verify functionality.
🔧 Temporary Workarounds
Network Segmentation
windowsRestrict access to port 8000/TCP to only trusted management networks
Windows Firewall: New-NetFirewallRule -DisplayName "Block TeleControl Port" -Direction Inbound -LocalPort 8000 -Protocol TCP -Action Block
Authentication Hardening
allImplement strong authentication controls and monitor for suspicious login attempts
🧯 If You Can't Patch
- Implement strict network access controls to limit access to port 8000 to only absolutely necessary systems
- Deploy web application firewall (WAF) with SQL injection protection rules in front of the application
🔍 How to Verify
Check if Vulnerable:
Check TeleControl Server Basic version in application interface or installation directory. If version is below V3.1.2.2 and port 8000 is accessible, system is vulnerable.Check Version:
Check application GUI or installation directory for version informationVerify Fix Applied:
Verify application version shows V3.1.2.2 or higher in the interface or about dialog.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed authentication attempts followed by successful login
- Unexpected database access patterns
Network Indicators:
- SQL injection patterns in traffic to port 8000
- Unusual outbound connections from TeleControl Server process
SIEM Query:
source="telecontrol.log" AND ("sql" OR "database" OR "query") AND ("error" OR "exception" OR "malformed")
