## What is CVE-2019-3567?

CVE-2019-3567 is a high-severity path traversal vulnerability in Facebook osquery, published on 3 Jun 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In some configurations an attacker can inject a new executable path into the extensions.load file for osquery and hard link a parent folder of a malicious binary to a folder with known 'safe' permissions. Under those circumstances osquery will load said malicious executable with SYSTEM permissions. The solution is to migrate installations to the 'Program Files' directory on Windows which restricts unprivileged write access. This issue affects osquery prior to v3.4.0.

Weakness: CWE-59 (Improper Link Resolution Before File Access), CWE-284 (Improper Access Control)

Check this codebase for CVE-2019-3567 and fix it if it is affected.

What it is: CVE-2019-3567 is a high-severity path traversal vulnerability in Facebook osquery, published on 3 Jun 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-2019-3567 in the wild and no public exploit code.

Affected product: Facebook osquery. 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.
