## Affected

- Eppendorf BioFlo 320: all versions

## Description

Eppendorf BioFlo 320 is vulnerable due to VNC server using a hard-coded password. If a remote attacker knows the network address of any BioFlo 320 model with remote access enabled, they can gain full control of the user interface by using this password. Once connected, the attacker would have full access to all control panel features for the BioFlo 320. VNC traffic is not encrypted.
