## What is CVE-2018-6827?

CVE-2018-6827 is a high-severity vulnerability in n/a, published on 9 Feb 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

VOBOT CLOCK before 0.99.30 devices do not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information, and consequently execute arbitrary code, via a crafted certificate, as demonstrated by leveraging a hardcoded --no-check-certificate Wget option.

Weakness: CWE-295 (Improper Certificate Validation)

Check this codebase for CVE-2018-6827 and fix it if it is affected.

What it is: CVE-2018-6827 is a high-severity vulnerability in n/a, published on 9 Feb 2018. 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-2018-6827 in the wild and no public exploit code.

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.
