CVE-2025-3425

Unauthenticated code execution via permissive .NET deserialization

Published Apr 7, 2025 · Updated Apr 10, 2025

Deserialization of untrusted data in Philips IntelliSpace Portal 12 and earlier allows remote attackers to execute code through port 755. The .NET Remoting server accepts serialized objects with TypeFilterLevel set to Full, enabling unsafe object-graph instantiation. Exploitation requires adjacent-network access and active user interaction but no authentication, and successful attacks compromise the host.
