## What is CVE-2021-43282?

CVE-2021-43282 is a medium-severity vulnerability in n/a, published on 30 Nov 2021. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An issue was discovered on Victure WR1200 devices through 1.0.3. The default Wi-Fi WPA2 key is advertised to anyone within Wi-Fi range through the router's MAC address. The device default Wi-Fi password corresponds to the last 4 bytes of the MAC address of its 2.4 GHz network interface controller (NIC). An attacker within scanning range of the Wi-Fi network can thus scan for Wi-Fi networks to obtain the default key.

Weakness: CWE-798 (Use of Hard-coded Credentials)

Check this codebase for CVE-2021-43282 and fix it if it is affected.

What it is: CVE-2021-43282 is a medium-severity vulnerability in n/a, published on 30 Nov 2021. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-43282 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.
