Summary
A vulnerability has been identified in Siemens Software Center (All versions < V3.5.8.2), Simcenter 3D (All versions < V2506.6000), Simcenter Femap (All versions < V2506.0002), Simcenter STAR-CCM+ (All versions < V2602), Solid Edge SE2025 (All versions < V225.0 Update 13), Solid Edge SE2026 (All versions < V226.0 Update 04), Tecnomatix Plant Simulation (All versions < V2504.0008). Affected applications do not properly validate client certificates to connect to Analytics Service endpoint. This could allow an unauthenticated remote attacker to perform man in the middle attacks.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
