CVE-2024-3301Network attack vector

Authenticated code execution via unsafe .NET deserialization

Published May 30, 2024 · Updated Sep 3, 2024

Unsafe .NET object deserialization in Dassault Systèmes DELMIA Apriso 2019 through 2024 allows remote authenticated users to execute code. The product reconstructs attacker-controlled .NET objects without a disclosed validation boundary; the affected endpoint, class, method, and payload field remain unpublished. A valid low-privilege account, network reachability, and high-complexity conditions are required; successful exploitation runs attacker-controlled code across a changed security boundary.
