## What is CVE-2022-39812?

CVE-2022-39812 is a high-severity path traversal vulnerability in n/a, published on 27 Jan 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Italtel NetMatch-S CI 5.2.0-20211008 allows Absolute Path Traversal under NMSCI-WebGui/SaveFileUploader. An unauthenticated user can upload files to an arbitrary path. An attacker can change the uploadDir parameter in a POST request (not possible using the GUI) to an arbitrary directory. Because the application does not check in which directory a file will be uploaded, an attacker can perform a variety of attacks that can result in unauthorized access to the server.

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

Check this codebase for CVE-2022-39812 and fix it if it is affected.

What it is: CVE-2022-39812 is a high-severity path traversal vulnerability in n/a, published on 27 Jan 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-39812 exists.

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.
