## What is CVE-2019-19731?

CVE-2019-19731 is a high-severity path traversal vulnerability in n/a, published on 16 Dec 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Roxy Fileman 1.4.5 for .NET is vulnerable to path traversal. A remote attacker can write uploaded files to arbitrary locations via the RENAMEFILE action. This can be leveraged for code execution by uploading a specially crafted Windows shortcut file and writing the file to the Startup folder (because an incomplete blacklist of file extensions allows Windows shortcut files to be uploaded).

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

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-19731 and fix it if it is affected.

What it is: CVE-2019-19731 is a high-severity path traversal vulnerability in n/a, published on 16 Dec 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-2019-19731 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.
