## What is CVE-2018-16216?

CVE-2018-16216 is a high-severity command injection vulnerability in n/a, published on 25 Apr 2019. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A command injection (missing input validation, escaping) in the monitoring or memory status web interface in AudioCodes 405HD (firmware 2.2.12) VoIP phone allows an authenticated remote attacker in the same network as the device to trigger OS commands (like starting telnetd or opening a reverse shell) via a POST request to the web server. In combination with another attack (unauthenticated password change), the attacker can circumvent the authentication requirement.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

Check this codebase for CVE-2018-16216 and fix it if it is affected.

What it is: CVE-2018-16216 is a high-severity command injection vulnerability in n/a, published on 25 Apr 2019. 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-2018-16216 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.
