CVE-2025-30032
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected application is vulnerable to SQL injection through the internally used 'UpdateDatabaseSettings' method. This could allow an authenticated remote attacker to bypass authorization controls, to read from and write to the application's database and execute code with "NT AUTHORITY\NetworkService" permissions. A successful attack requires the attacker to be able to access port 8000 on a system where a vulnerable version of the affected application is executed on. (ZDI-CAN-25921)

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if TeleControl Server Basic is installedCheck the system for TeleControl Server Basic installation by looking for the application in Program Files, or check Windows Services for 'TeleControl Server' or similar Siemens-related services.Affected if The application is present on the system.
-
Determine the installed versionLocate the TeleControl Server Basic installation directory and check for a version file, or right-click the main executable and view Properties > Details for the File Version. Compare against the affected range of versions before 3.1.2.2.Affected if The installed version is lower than 3.1.2.2.
-
Verify the UpdateDatabaseSettings method is accessibleCheck if the web interface or API endpoint for UpdateDatabaseSettings is exposed. This is typically accessible through the server's web service on port 8000 as mentioned in the context.Affected if The UpdateDatabaseSettings method is accessible without additional authorization controls.
-
Check network exposure of port 8000Use netstat or a port scanner to verify if port 8000 is listening and accessible from the network. Review firewall rules to determine if this port is exposed to untrusted networks.Affected if Port 8000 is open and accessible from untrusted network segments.
A user is affected if TeleControl Server Basic is installed with a version lower than 3.1.2.2 and the UpdateDatabaseSettings interface on port 8000 is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.1.2.2
Upgrade to version V3.1.2.2 or later. As an interim measure, restrict network access to port 8000 and implement WAF rules to detect SQL injection patterns.
TeleControl Server Basic V3.1.2.2
- Obtain TeleControl Server Basic version 3.1.2.2 or later from the Siemens cert-portal or official Siemens distribution channels
- Follow Siemens standard upgrade procedure for TeleControl Server Basic to apply the update
- After upgrading, verify the version is V3.1.2.2 or higher in the application interface
- As a defense-in-depth measure, restrict access to port 8000 to only authorized personnel and trusted network segments
