CVE-2022-31248
SUMA user enumeration via weak error message
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. This information disclosure vulnerability (CWE-204) requires only network access and no authentication, facilitating subsequent targeted attacks.
