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.
