Unauthenticated code execution via SOAP object deserialization
Published Jun 2, 2025 · Updated Feb 26, 2026
Deserialization in DELMIA Apriso Release 2020 through Release 2025 allows remote attackers to execute code through its SOAP service. The FlexNetOperationsService Invoke endpoint deserializes attacker-controlled .NET object graphs, allowing gadget chains to invoke XamlReader.Parse and execute an embedded Windows payload. No authentication or user interaction is required, but exploitation has high complexity; successful execution compromises the application server.
