Beschreibung
A Deserialization of Untrusted Data vulnerability affecting SIMULIA Execution Engine from Release 2023 through Release 2026 could lead to an unauthenticated remote code execution.

Threat-Hunting-Queries
Die Schwachstelle ist eine Deserialization of Untrusted Data, die zu Remote Code Execution (RCE) führen kann. Die Detektion sollte sich auf ungewöhnliche Prozessstarts oder Netzwerkverbindungen konzentrieren, die von der SIMULIA Execution Engine ausgehen, insbesondere solche, die auf Shell-Befehle oder Skriptausführung hindeuten.
