# ABB Ability Edgenius: missing authentication on a critical function

ABB Ability Edgenius through 3.2.3.0 exposes a critical function without requiring authentication. An attacker who can reach the service may invoke that function without logging in.

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

## How to check

- Confirm the installed Edgenius version is `3.2.3.0` or earlier
- Check whether the Edgenius service is reachable from untrusted networks
- Details of the affected function are unknown from the sources

## Fix

- Upgrade ABB Ability Edgenius to a version later than `3.2.3.0` once the vendor publishes it (fixed version unknown from the sources)
- Restrict network access to the Edgenius service until patched
