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 'UnlockWebServerGatewaySettings' 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 (versions < V3.1.2.2) via the UnlockWebServerGatewaySettings method allows authenticated remote attackers to bypass authorization, read/write to the application's database, and execute code with NT AUTHORITY\NetworkService privileges. Exploitation requires network access to port 8000.

MitigationUpgrade TeleControl Server Basic to version V3.1.2.2 or later to remediate this vulnerability. Restrict network access to port 8000 as a compensating control until patching is complete.

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 installation
    Locate the TeleControl Server Basic software on the system. Check common installation paths such as C:\Program Files\Siemens\TeleControl Server Basic or review installed programs via Windows Control Panel > Programs and Features.
    Affected if TeleControl Server Basic is installed on the system.
  2. Identify installed version
    Right-click the TeleControl Server Basic application or service in Programs and Features, select Properties, and note the version. Alternatively, check the version displayed in the application's About or Help section.
    Affected if The installed version is lower than V3.1.2.2.
  3. Verify port 8000 is listening
    Open Command Prompt and run: netstat -an | findstr :8000 or use PowerShell: Get-NetTCPConnection -LocalPort 8000. This port hosts the web interface required for exploitation.
    Affected if Port 8000 is listening and accepting connections, indicating the vulnerable web service is active.
  4. Assess network accessibility of the web interface
    From a remote system, attempt to reach http://<target>:8000 or use telnet <target> 8000 to confirm the web gateway is network-accessible.
    Affected if The TeleControl Server Basic web interface on port 8000 is reachable from network segments beyond the local host.

A user is affected if TeleControl Server Basic version lower than V3.1.2.2 is installed with the web interface on port 8000 exposed to the network.
