Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Luanox is a module host for Lua packages. Prior to 0.1.1, a file traversal vulnerability can cause potential denial of service by overwriting Phoenix runtime files. Package names like ../../package are not properly filtered and pass the validity check of the rockspec verification system. This causes the uploaded file to be stored at the relative path location. If planned carefully, this could overwrite a runtime file and cause the website to crash. This vulnerability is fixed by 0.1.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-22

A file path is built from user input without being confined, so sequences like “../” let an attacker step outside the intended directory. That can expose configuration, credentials, or source code, and in the worst case lets an attacker write files where they shouldn't. A durable fix resolves and canonicalises the path, then rejects anything that escapes a known-safe base directory.

Recommended fix High confidence

Upgrade to luanox version 0.1.1 or later

  1. 1. Identify the current installed version of Luanox by checking your project dependencies (e.g., in your rockspec file or package.json)
  2. 2. Update your dependency to specify version 0.1.1 or later
  3. 3. Run your package manager to fetch and install the updated version (e.g., luarocks install luanox or relevant package manager command)
  4. 4. Verify the new version is installed correctly
  5. 5. Test that your application still functions normally after the upgrade
  6. 6. If you have a deployment pipeline, redeploy with the updated dependency
Caveat Review the changelog between your current version and 0.1.1 to check for any breaking changes in functionality
