Summary

A vulnerability has been identified in COMOS V10.6 (All versions < V10.6.1), COMOS V10.6 (All versions < V10.6.1), NX V2412 (All versions < V2412.8700), NX V2506 (All versions < V2506.6000), Simcenter 3D (All versions < V2506.6000), Simcenter Femap (All versions < V2506.0002), Solid Edge SE2025 (All versions < V225.0 Update 10), Solid Edge SE2026 (All versions < V226.0 Update 1). The IAM client in affected products is missing server certificate validation while establishing TLS connections to the authorization server. This could allow an attacker to perform a man-in-the-middle attack.
