CVE-2025-23364
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 TIA Administrator (All versions < V3.0.6). The affected application improperly validates code signing certificates. This could allow an attacker to bypass the check and exceute arbitrary code during installations.
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 confidenceTIA Administrator fails to properly validate code signing certificates, allowing attackers to bypass the signature verification mechanism. This enables execution of malicious code during the installation process by presenting a crafted or improperly signed executable.

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.
-
Locate TIA Administrator installationCheck for the Siemens TIA Administrator installation directory, typically under C:\Program Files\Siemens\TIA Administrator or C:\Program Files (x86)\Siemens\TIA Administrator. Also verify presence in Windows Add/Remove Programs.Affected if TIA Administrator is installed on the system
-
Determine installed TIA Administrator versionOpen the TIA Administrator application and navigate to Help > About, or right-click the executable file, select Properties, and check the Details tab for the Product Version. Alternatively, check the version in the Windows registry under HKLM\SOFTWARE\Siemens\TIAAdministrator or HKLM\SOFTWARE\WOW6432Node\Siemens\TIAAdministrator.Affected if The displayed version number is lower than 3.0.6 (for example, 3.0.5, 3.0.4, or earlier)
-
Verify installation componentsConfirm that the TIA Administrator installation includes the software component used for loading or installing additional software packages, as this is the component where the code signing validation occurs.Affected if The installation feature for loading packages or updates is present and active in the TIA Administrator environment
-
Check for recent installation or update activityReview Windows Event Logs under Application and System for recent TIA Administrator installation events, or check the TIA Administrator update history if accessible through the interface.Affected if Recent installations or updates were performed using TIA Administrator versions prior to V3.0.6
The system is affected if TIA Administrator version is installed and the version number is lower than 3.0.6, making the code signing certificate validation vulnerable to bypass.

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 · scoped3.0.6
Update TIA Administrator to version V3.0.6 or later to obtain the patched certificate validation logic.
TIA Administrator V3.0.6
- 1. Identify the current installed version of TIA Administrator
- 2. Navigate to the official Siemens cert-portal.siemens.com to obtain the fixed version V3.0.6
- 3. Download and install TIA Administrator V3.0.6 to replace the vulnerable version
- 4. Verify the installation was successful and the version is now V3.0.6
