An improper access control information disclosure vulnerability in Trend Micro Apex One and OfficeScan XG SP1 could allow an unauthenticated user to connect to the product server and reveal version, build and patch information.
Does this matter?
Lower severity and a low EPSS score (3.25%). Track it; it rarely justifies an emergency change on its own.
