CVE-2025-32825
📋 TL;DR
An SQL injection vulnerability in TeleControl Server Basic allows authenticated attackers to bypass authorization, read/write to the database, and execute code with NetworkService permissions. This 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
Full system compromise with code execution as NT AUTHORITY\NetworkService, allowing lateral movement, data theft, and persistence.
Likely Case
Database manipulation, credential theft, and privilege escalation leading to operational disruption.
If Mitigated
Limited impact with proper network segmentation and authentication controls, potentially only unauthorized data access.
🎯 Exploit Status
SQL injection via GetProjects method requires authenticated access but is straightforward once authenticated.
🛠️ 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 support portal. 2. Backup configuration and data. 3. Install update following vendor documentation. 4. Restart TeleControl Server Basic service.
🔧 Temporary Workarounds
Network Access Restriction
windowsRestrict access to port 8000/TCP to only trusted IP addresses or networks.
Windows Firewall: New-NetFirewallRule -DisplayName "Block TeleControl Port" -Direction Inbound -LocalPort 8000 -Protocol TCP -Action Block
Application Layer Filtering
allImplement WAF rules to block SQL injection patterns targeting the GetProjects method.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate TeleControl Server Basic from untrusted networks.
- Enforce strong authentication mechanisms and monitor for unusual database queries or authentication attempts.
🔍 How to Verify
Check if Vulnerable:
Check TeleControl Server Basic version in application interface or registry: HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\TeleControl Server Basic\VersionCheck Version:
reg query "HKLM\SOFTWARE\Siemens\TeleControl Server Basic" /v VersionVerify Fix Applied:
Confirm version is V3.1.2.2 or higher and test GetProjects functionality with SQL injection test payloads.📡 Detection & Monitoring
