## What is CVE-2025-34414?

CVE-2025-34414 is a critical unsafe deserialization vulnerability in Entrust Corporation Instant Financial Issuance (IF), published on 9 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Entrust Instant Financial Issuance (IFI) On Premise software (formerly referred to as CardWizard) versions 5.x, prior to 6.10.5, and prior to 6.11.1 contain an insecure .NET Remoting exposure in the Legacy Remoting Service that is enabled by default. The service registers a TCP remoting channel with SOAP and binary formatters configured at TypeFilterLevel=Full and exposes default ObjectURI endpoints such as logfile.rem, photo.rem, cwPhoto.rem, and reports.rem on a network-reachable remoting port. A remote, unauthenticated attacker who can reach the remoting port can invoke exposed remoting objects to read arbitrary files from the server and coerce outbound authentication, and may achieve arbitrary file write and remote code execution via known .NET Remoting exploitation techniques. This can lead to disclosure of sensitive installation and service-account data and compromise of the affected host.

Weakness: CWE-502 (Deserialization of Untrusted Data), CWE-306 (Missing Authentication for Critical Functionality)

Affected product: Entrust Corporation Instant Financial Issuance (IF). 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.
