CVE-2025-32849
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 'UnlockSmtpSettings' 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 the UnlockSmtpSettings method of TeleControl Server Basic allows authenticated remote attackers to bypass authorization and execute arbitrary SQL queries against the application's database. This can lead to unauthorized data access/modification and remote code execution 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 versionLocate the installation directory and check the version file, or use the system's program information to identify the installed version of TeleControl Server Basic.Affected if The installed version is lower than 3.1.2.2 (e.g., 3.1.1, 3.0.x, or earlier).
-
Verify port 8000 exposureUse a network scanning tool or examine firewall rules to determine if port 8000 (the default TeleControl Server port) is accessible from untrusted networks.Affected if Port 8000 is exposed to the internet or untrusted network segments without firewall restrictions.
-
Check web service availabilityAccess the TeleControl Server Basic web interface on port 8000 and verify whether the UnlockSmtpSettings method endpoint is reachable via HTTP/HTTPS.Affected if The web service on port 8000 is accessible and responds to requests.
-
Confirm authentication stateReview active user accounts and sessions in TeleControl Server Basic to determine if any accounts exist that could be exploited by an authenticated attacker.Affected if There are active user accounts configured in TeleControl Server Basic, allowing authenticated access to the vulnerable method.
You are affected if TeleControl Server Basic version is below 3.1.2.2 and the service is accessible on port 8000 with valid user accounts present.

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 version V3.1.2.2 or later. As an interim compensating control, restrict network access to port 8000 through firewall rules or network segmentation.
TeleControl Server Basic V3.1.2.2
- Verify current installed version of TeleControl Server Basic
- Download TeleControl Server Basic version 3.1.2.2 or later from the official Siemens portal
- Ensure you have a complete database backup before proceeding with the upgrade
- Stop the TeleControl Server Basic service
- Install the updated version 3.1.2.2
- Restart the TeleControl Server Basic service
- Verify the application is running correctly and the service is accessible on port 8000
