Vulnerability from github – Published: 2022-01-22 00:00 – Updated: 2022-01-28 00:03

Details

Fresenius Kabi Agilia Link + version 3.0 does not enforce transport layer encryption. Therefore, transmitted data may be sent in cleartext. Transport layer encryption is offered on Port TCP/443, but the affected service does not perform an automated redirect from the unencrypted service on Port TCP/80 to the encrypted service.
