CVE-2025-30030
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 'ImportDatabase' 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. (ZDI-CAN-25924)
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 (versions before V3.1.2.2) through the ImportDatabase method allows authenticated remote attackers to bypass authorization, read/write the database, and execute code with NT AUTHORITY\NetworkService permissions.

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 versionLocate the installed TeleControl Server Basic application and check its version information, typically found in the program files directory, about dialog, or Windows Programs and Features. Compare the installed version to the affected range of versions before V3.1.2.2.Affected if The installed version is any version prior to V3.1.2.2
-
Verify ImportDatabase method exposureDetermine if the ImportDatabase method is exposed and accessible on the TeleControl Server Basic instance. This typically involves checking the application configuration or API endpoints that expose this functionality.Affected if The ImportDatabase method is accessible without additional authorization controls beyond basic authentication
-
Confirm authentication is in useReview the authentication configuration for TeleControl Server Basic to confirm that user authentication is enabled and properly configured for remote access.Affected if Authentication is enabled but the ImportDatabase method can be accessed by any authenticated user without additional role-based access controls
-
Check network exposure of port 8000Examine firewall rules and network configuration to determine if port 8000 (the default TeleControl Server Basic port) is exposed to untrusted networks or the public internet.Affected if Port 8000 is accessible from untrusted networks or the internet
Your environment is affected if TeleControl Server Basic version is before V3.1.2.2, the ImportDatabase method is accessible, and port 8000 is exposed to untrusted networks.

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; until then, restrict access to port 8000 to trusted networks and limit authentication privileges.
TeleControl Server Basic V3.1.2.2
- Upgrade TeleControl Server Basic to version 3.1.2.2 or later.
- After upgrading, verify that the application runs correctly and the ImportDatabase method functions as expected.
- Confirm that the system is accessible only on intended network segments, as the vulnerability requires access to port 8000.
