In short
The system reveals different error messages when you try to log in with an existing username versus a non-existent one, allowing attackers to discover valid usernames without needing a password.
Technical detail
An observable response discrepancy in SUSE Manager's authentication mechanism (spacewalk-java) permits unauthenticated remote attackers to enumerate valid usernames by analyzing differential error messages.
