CVE-2025-32841
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 'UnlockGateway' 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 confidenceA SQL injection vulnerability exists in TeleControl Server Basic (versions < V3.1.2.2) within the 'UnlockGateway' method. An authenticated remote attacker who can reach port 8000 can exploit this to bypass authorization, read/write to the database, and execute code with NT AUTHORITY\NetworkService privileges.

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.
-
Determine TeleControl Server Basic versionOpen the TeleControl Server Basic application or check the Windows Programs and Features list to locate the installed version numberAffected if The installed version is lower than V3.1.2.2
-
Check if port 8000 is listeningRun the command 'netstat -an | findstr :8000' or use a port scanner locally to determine if port 8000 is in a listening stateAffected if Port 8000 is open and accepting connections on any interface
-
Verify service accessibilityAttempt to reach the TeleControl Server Basic service endpoint on port 8000 using a tool like curl or telnet from an internal systemAffected if The service responds on port 8000, indicating it is network-accessible
-
Confirm authentication configurationReview TeleControl Server Basic security settings to verify if authentication is required for the UnlockGateway methodAffected if The UnlockGateway method does not enforce proper authentication or uses vulnerable authentication logic
The environment is affected if TeleControl Server Basic version is below V3.1.2.2 AND the service is accessible on port 8000 from the network.
Generated from the published advisory. Verify against your own configuration.
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. As an interim control, restrict network access to port 8000 to trusted IP addresses only.
V3.1.2.2
- 1. Ensure you have a backup of the current TeleControl Server Basic installation and its database.
- 2. Verify the current installed version of TeleControl Server Basic to confirm it is below V3.1.2.2.
- 3. Download the fixed version V3.1.2.2 from the official Siemens cert-portal or Siemens industrial security website.
- 4. Stop the TeleControl Server Basic service to ensure no active connections during the upgrade.
- 5. Install V3.1.2.2 following the standard Siemens installation procedures for TeleControl Server Basic.
- 6. After installation, restart the TeleControl Server Basic service.
- 7. Verify the upgrade was successful by checking the application version and testing basic functionality.
- 8. Confirm that port 8000 is still accessible only to authorized users and that network segmentation is in place as an additional defense layer.
