Eppendorf BioFlo 320 is vulnerable to 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.

Fixes

Solution

Eppendorf has released a software update that permanently removes VNC access from the controller. Users should download and apply this update from: https://www.eppendorf.com/software-downloads. https://www.eppendorf.com/software-downloads All affected BioFlo 320 systems always shipped with Virtual Network Computing (VNC) disabled by default, and VNC can only be enabled locally at the tower. Eppendorf has removed VNC configuration information from all current documentation, so it no longer appears in BioFlo 320 Operating Manuals. Eppendorf recommends user do the following: - Verify that VNC is disabled on the controller - Enable security so that only Admin and Supervisor roles can change VNC settings - Install Version 5.0 Software as soon as possible


Workaround
