CVE-2026-7251 Details
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.
A vulnerability exists in the Eppendorf BioFlo 320 bioreactor due to the VNC server employing a hard-coded password. This issue allows remote attackers to gain full control of the user interface on models with remote access enabled, provided they know the network address of the device. The exploitation is facilitated by the fact that VNC traffic is unencrypted, leaving all control panel features accessible to the attacker.
Eppendorf has released a software update that removes VNC access from the controller. Users should download and apply this update from the Eppendorf Software Downloads page. Additionally, users are advised to verify that VNC is disabled on the controller, enable security settings to restrict VNC configuration changes to Admin and Supervisor roles, and install Version 5.0 Software as soon as possible.
