CVE-2025-3424

Unauthenticated file read via crafted .NET Remoting URLs

Published Apr 7, 2025 · Updated Apr 10, 2025

Path traversal in Philips IntelliSpace Portal 12 and prior allows remote attackers to read internal server files through crafted .NET Remoting URLs. The .NET Remoting TCP channel on port 755 marshals attacker-crafted URLs derived from client-side configuration data and resolves them to internal filesystem paths without enforcing a restricted directory. The endpoint is reachable from an adjacent network without authentication, and successful exploitation discloses internal server-file contents.
