## What is CVE-2022-1359?

CVE-2022-1359 is a medium-severity path traversal vulnerability in Cambium Networks cnMaestro, published on 17 May 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The affected On-Premise cnMaestro is vulnerable to an arbitrary file-write through improper limitation of a pathname to a restricted directory inside a specific route. If an attacker supplied path traversal charters (../) as part of a filename, the server will save the file where the attacker chooses. This could allow an attacker to write any data to any file in the server.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

Check this codebase for CVE-2022-1359 and fix it if it is affected.

What it is: CVE-2022-1359 is a medium-severity path traversal vulnerability in Cambium Networks cnMaestro, published on 17 May 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-1359 in the wild and no public exploit code.

Affected product: Cambium Networks cnMaestro. 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.
