## What is CVE-2025-3425?

CVE-2025-3425 is a high-severity unsafe deserialization vulnerability in Philips IntelliSpace Portal, published on 7 Apr 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

The IntelliSpace portal application utilizes .NET Remoting for its functionality. The vulnerability arises from the exploitation of port 755 through the deserialization vulnerability. After analyzing the configuration files, we observed that the server had set the TypeFilterLevel to Full which is dangerous as it can potentially lead to remote code execution using deserialization. This issue affects IntelliSpace Portal: 12 and prior.

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2025-3425 and fix it if it is affected.

What it is: CVE-2025-3425 is a high-severity unsafe deserialization vulnerability in Philips IntelliSpace Portal, published on 7 Apr 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-3425 in the wild and no public exploit code.

Affected product: Philips IntelliSpace Portal. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
