CVE-2024-39563 is a medium-severity command injection vulnerability in Juniper Junos Space, published on 11 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A Command Injection vulnerability in Juniper Networks Junos Space allows an unauthenticated, network-based attacker sending a specially crafted request to execute arbitrary shell commands on the Junos Space Appliance, leading to remote command execution by the web application, gaining complete control of the device.

Check this codebase for CVE-2024-39563 and fix it if it is affected.

What it is: CVE-2024-39563 is a medium-severity command injection vulnerability in Juniper Junos Space, published on 11 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-39563 in the wild and no public exploit code.

Affected product: Juniper Junos Space. 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.
