CVE-2025-40745 — Siemens Simcenter 3D security vulnerability

Medium CVSS 6.3

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.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
