# Moxa industrial computers: missing authorization exposes secrets API to low-privileged users

Some Moxa industrial computing products expose an internal API endpoint at /api/v1/secrets/ without an authorization check. An authenticated low-privileged user on an adjacent network can read sensitive data, including cryptographic key material.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

A missing authorization vulnerability exists in the internal API `/api/v1/secrets/` of some of Moxa's industrial computing products. A low-privileged authenticated attacker with adjacent network access could exploit this vulnerability to access sensitive information, potentially resulting in the disclosure of confidential data, including cryptographic key material.
