MEDIUM 5.3EPSS 7.77%
Does this matter?
Lower severity and a low EPSS score (7.77%). Track it; it rarely justifies an emergency change on its own.
Description
Accellion FTP server prior to version FTA_9_12_220 only returns the username in the server response if the username is invalid. An attacker may use this information to determine valid user accounts and enumerate them.
