## What is CVE-2019-14450?

CVE-2019-14450 is a critical path traversal vulnerability in n/a, published on 28 Oct 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A directory traversal vulnerability was discovered in RepetierServer.exe in Repetier-Server 0.8 through 0.91 that allows for the creation of a user controlled XML file at an unintended location. When this is combined with CVE-2019-14451, an attacker can upload an "external command" configuration as a printer configuration, and achieve remote code execution. After exploitation, loading of the external command configuration is dependent on a system reboot or service restart.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-14450 and fix it if it is affected.

What it is: CVE-2019-14450 is a critical path traversal vulnerability in n/a, published on 28 Oct 2019. 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-2019-14450 in the wild and no public exploit code.

Affected product: n/a. 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.
