CVE-2025-32839
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 'GetGateways' 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in TeleControl Server Basic's GetGateways method allows authenticated remote attackers to bypass authorization, read/write to the database, and execute code with NT AUTHORITY\NetworkService privileges. Affected versions are all versions prior to V3.1.2.2.

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.
-
Confirm TeleControl Server Basic installationCheck installed programs on the system for 'Siemens Telecontrol Server Basic' or look for the installation directory. On Windows, check Programs and Features or the default install path.Affected if The product is present on the system and version cannot be determined or is below 3.1.2.2
-
Identify installed versionLocate version information in the installation directory, registry, or application logs. Compare the found version string to the affected range (any version prior to 3.1.2.2).Affected if Installed version is any build or release prior to V3.1.2.2
-
Verify port 8000 exposureCheck if port 8000 is listening and accessible. Use 'netstat -an | findstr 8000' or a port scanner from an external system to test connectivity.Affected if Port 8000 is open and reachable from untrusted network segments
-
Confirm service account contextCheck the Windows service configuration for TeleControl Server Basic to verify it runs under NT AUTHORITY\NetworkService or another low-privilege account.Affected if Service runs with elevated privileges or as NT AUTHORITY\NetworkService with network exposure
-
Audit GetGateways method accessibilityReview web service or API configuration files to confirm the GetGateways method endpoint is exposed without additional authorization controls beyond basic authentication.Affected if GetGateways method is accessible to authenticated users without role-based restrictions
The environment is affected if Siemens Telecontrol Server Basic is installed with any version prior to 3.1.2.2 and 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
Primary mitigation is upgrading to V3.1.2.2 or later. As a compensating control, restrict network access to port 8000 to only trusted IPs and follow least-privilege principles for the service account.
V3.1.2.2
- Verify the currently installed TeleControl Server Basic version by checking the application or system information
- Back up the current TeleControl Server Basic configuration and database
- Obtain the fixed version V3.1.2.2 or later from the official Siemens cert-portal or appropriate Siemens update channel
- Stop the TeleControl Server Basic service to ensure a clean upgrade process
- Install version 3.1.2.2 of TeleControl Server Basic following the official installation documentation
- After installation, verify the new version number matches V3.1.2.2 or later
- Restart the TeleControl Server Basic service
- Confirm the application is functioning correctly and the GetGateways method is no longer vulnerable to SQL injection
