CVE-2001-1280
POP3 Server for Ipswitch IMail 7.04 and earlier generates different responses to valid and invalid user names, which allows remote attackers to determine users on the system.
Does this matter?
Lower severity and a low EPSS score (2.19%). Track it; it rarely justifies an emergency change on its own.
