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 · unedited
A 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 'ExportCertificate' 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 confidence

SQL injection vulnerability in TeleControl Server Basic's 'ExportCertificate' method allows authenticated attackers to bypass authorization, read/write to the database, and execute code with NT AUTHORITY\NetworkService permissions. Exploitation requires network access to port 8000.

MitigationUpgrade to V3.1.2.2 or later to patch the SQL injection vulnerability, and limit network access to port 8000 to trusted users until the patch is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm TeleControl Server Basic is installed
    Check for the TeleControl Server Basic installation directory, typically under C:\Program Files\Siemens\ or look for the service named 'TeleControl Server Basic' in Windows Services (services.msc)
    Affected if The software is present on the system
  2. Identify installed version
    Check the version of TeleControl Server Basic by opening the application's About dialog, checking the executable properties (right-click on TCServerBasic.exe > Properties > Details), or reviewing installation logs
    Affected if The installed version is lower than 3.1.2.2
  3. Verify port 8000 is exposed
    Run 'netstat -an | findstr :8000' or use PowerShell 'Get-NetTCPConnection -LocalPort 8000' to check if the service is listening on port 8000. Also check firewall rules with 'netsh advfirewall firewall show rule name=all' for any rules allowing port 8000
    Affected if Port 8000 is open and listening on network interfaces accessible to untrusted users
  4. Check if authentication is required for the ExportCertificate method
    Review the application's user authentication configuration and ensure the ExportCertificate method requires valid credentials. Examine the application's user management console or configuration files for authentication settings
    Affected if The ExportCertificate method can be accessed without proper authentication or with low-privilege accounts

You are affected if TeleControl Server Basic is installed with a version lower than 3.1.2.2 AND port 8000 is accessible from untrusted network paths
