CVE-2025-40744
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 Solid Edge SE2025 (All versions < V225.0 Update 11). Affected applications do not properly validate client certificates to connect to License Service endpoint. This could allow an unauthenticated remote attacker to perform man in the middle attacks.
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 confidenceSolid Edge SE2025 client applications fail to properly validate client certificates when connecting to the License Service endpoint. This allows an attacker positioned on the network to intercept the connection and impersonate the license server, enabling man-in-the-middle attacks.

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.
-
Confirm Solid Edge SE2025 is installedCheck for Solid Edge SE2025 in the installed programs list or Program Files directoryAffected if Solid Edge SE2025 is installed and the version is prior to V225.0 Update 11
-
Identify the installed Solid Edge versionOpen Solid Edge SE2025 and navigate to Help > About Solid Edge, or check the installed version through Windows Programs and FeaturesAffected if The displayed version is earlier than V225.0 Update 11 (for example, V225.0.0 through V225.0.10)
-
Determine if License Service connection is configuredCheck the license configuration settings within Solid Edge or the license server settings to see if the License Service endpoint is being usedAffected if The client is configured to connect to a License Service endpoint for license validation
-
Verify the client certificate validation behaviorAttempt to observe the license connection process through network monitoring or check the license configuration for any certificate validation settingsAffected if The connection proceeds without validating the client certificate from the license server, indicating the vulnerability is present
A user is affected if Solid Edge SE2025 is installed with a version prior to V225.0 Update 11 and is configured to connect to a License Service endpoint.

dbcve · scopedUpdate to Solid Edge SE2025 V225.0 Update 11 or later, which implements proper client certificate validation for License Service connections.
Solid Edge SE2025 V225.0 Update 11
- 1. Identify the current Solid Edge SE2025 version installed in the environment
- 2. Navigate to the Siemens cert-portal or official Siemens support website to obtain the V225.0 Update 11 patch
- 3. Download the V225.0 Update 11 package for Solid Edge SE2025
- 4. Apply the update by following Siemens standard installation procedures for patch deployment
- 5. Verify the installation was successful by checking the Solid Edge SE2025 version (should show V225.0 Update 11 or later)
- 6. Test that the License Service endpoint connection is functioning properly with proper certificate validation
