CVE-2025-32855
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 'UnlockOpcSettings' 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 'UnlockOpcSettings' method allows authenticated remote attackers to bypass authorization, read/write to the database, and execute code with NT AUTHORITY\NetworkService permissions via port 8000.

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 by reviewing installed programs, services, or checking for the application directory structureAffected if The software is installed on the system
-
Determine installed versionLocate the version information for TeleControl Server Basic (typically accessible via the application, its documentation, or system registry) and compare it to the affected range: versions lower than 3.1.2.2 are vulnerableAffected if The installed version is lower than 3.1.2.2
-
Verify port 8000 accessibilityCheck if port 8000 is listening and accessible on the system using network scanning tools or by reviewing firewall rules and listening servicesAffected if Port 8000 is exposed and reachable from untrusted networks
-
Confirm UnlockOpcSettings method exposureDetermine if the UnlockOpcSettings API method is accessible on the TeleControl Server Basic instance (typically via HTTP/HTTPS on port 8000)Affected if The UnlockOpcSettings endpoint is accessible without additional access controls
-
Verify authentication configurationReview the authentication settings for the TeleControl Server Basic web interface or API to determine if attacker authentication is possibleAffected if Authentication can be obtained or bypassed, allowing access to the vulnerable method
A user is affected if TeleControl Server Basic version lower than 3.1.2.2 is installed with port 8000 accessible and the UnlockOpcSettings method exposed to potential attackers.

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 to TeleControl Server Basic V3.1.2.2 or later to patch the SQL injection vulnerability; restrict network access to port 8000 as an additional defense layer.
V3.1.2.2 or later
- Obtain TeleControl Server Basic version 3.1.2.2 or later from the official Siemens support portal (cert-portal.siemens.com)
- Follow the standard upgrade procedure documented in the Siemens installation/upgrade guide for TeleControl Server Basic
- After upgrading, verify the application is running version 3.1.2.2 or later
- Ensure port 8000 is protected by appropriate network access controls to limit exposure
