## What is CVE-2025-34082?

CVE-2025-34082 is a critical command injection vulnerability in IGEL Technology GmbH OS, published on 3 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A command injection vulnerability exists in IGEL OS versions prior to 11.04.270 within the Secure Terminal and Secure Shadow services. The flaw arises due to improper input sanitization in the handling of specially crafted PROXYCMD commands on TCP ports 30022 and 5900.

Check this codebase for CVE-2025-34082 and fix it if it is affected.

What it is: CVE-2025-34082 is a critical command injection vulnerability in IGEL Technology GmbH OS, published on 3 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34082 exists.

Affected product: IGEL Technology GmbH OS. 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.
