Terumo Blood and Cell Technologies published a product security bulletin on Apache Log4j (CVE-2021-44228) on April 13, 2022. It lists the Vista Information System with Oracle 12.2 for Vista Information System v4.0 SP2 and v4.2 as affected, and some assessments of other products were still ongoing.
Customers should contact their service representative about mitigation. The bulletin names the affected configurations by their Oracle 12.2 database release, so the inventory question is which Vista installs run on it.
