## What is CVE-2023-5938?

CVE-2023-5938 is a high-severity path traversal vulnerability in Nozomi Networks Arc, published on 15 May 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Multiple functions use archives without properly validating the filenames therein, rendering the application vulnerable to path traversal via 'zip slip' attacks.

An administrator able to provide tampered archives to be processed by the affected versions of Arc may be able to have arbitrary files extracted to arbitrary filesystem locations. Leveraging this issue, an attacker may be able to overwrite arbitrary files on the target filesystem and cause critical impacts on the system (e.g., arbitrary command execution on the victim’s machine).

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

Check this codebase for CVE-2023-5938 and fix it if it is affected.

What it is: CVE-2023-5938 is a high-severity path traversal vulnerability in Nozomi Networks Arc, published on 15 May 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-5938 in the wild and no public exploit code.

Affected product: Nozomi Networks Arc. 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.
