## What is CVE-2022-23227?

CVE-2022-23227 is a critical missing authorization vulnerability in n/a, published on 14 Jan 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

NUUO NVRmini2 through 3.11 allows an unauthenticated attacker to upload an encrypted TAR archive, which can be abused to add arbitrary users because of the lack of handle_import_user.php authentication. When combined with another flaw (CVE-2011-5325), it is possible to overwrite arbitrary files under the web root and achieve code execution as root.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Check this codebase for CVE-2022-23227 and fix it if it is affected.

What it is: CVE-2022-23227 is a critical missing authorization vulnerability in n/a, published on 14 Jan 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: Yes. Attackers have exploited CVE-2022-23227 in the wild since at least 18 Dec 2024.

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.
