CVE-2025-31351
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 'CreateProject' 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-25917)

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 TeleControl Server Basic installationCheck for TeleControl Server Basic software on the system using system inventory tools or by reviewing installed programs in the operating systemAffected if The software is present on the system
-
Determine installed versionLocate the installed version of TeleControl Server Basic by checking the application files, registry entries, or version information provided by the software itselfAffected if The installed version is lower than 3.1.2.2 (for example, 3.1.0.0 or any version below 3.1.2.2)
-
Check network exposure on port 8000Verify if the TeleControl Server Basic service is listening on port 8000 by using network scanning tools or checking open ports on the hostAffected if Port 8000 is open and the service is accessible over the network
A system is affected if TeleControl Server Basic is installed with a version lower than 3.1.2.2 and the service is accessible via port 8000, allowing remote attackers to reach the CreateProject method.

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 TeleControl Server Basic to version V3.1.2.2 or later to patch the SQL injection vulnerability.
V3.1.2.2
- Backup the TeleControl Server Basic installation and database before proceeding with any changes
- Obtain TeleControl Server Basic version V3.1.2.2 or later from the official Siemens download portal (cert-portal.siemens.com)
- Stop the TeleControl Server Basic service to ensure no active connections during the upgrade
- Install version V3.1.2.2 or later following the Siemens upgrade documentation
- Restart the TeleControl Server Basic service
- Verify the application is running correctly and the CreateProject method functions as expected
- Review application logs to confirm no SQL injection errors or suspicious activity
