## What is CVE-2023-20112?

CVE-2023-20112 is a high-severity vulnerability in Cisco Aironet Access Point Software, published on 23 Mar 2023. 

### Official description

A vulnerability in Cisco access point (AP) software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of certain parameters within 802.11 frames.

Check this codebase for CVE-2023-20112 and fix it if it is affected.

What it is: CVE-2023-20112 is a high-severity vulnerability in Cisco Aironet Access Point Software, published on 23 Mar 2023. 
Exploitation: There is no known exploitation of CVE-2023-20112 in the wild and no public exploit code.

Affected product: Cisco Aironet Access Point Software. 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.
