OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product
Отчет
Although a CVE was assigned upstream and Red Hat doesn't consider it to be a security flaw and won't receive any patch, also the CVE was made as disputed by MITRE. Considering that Red Hat is closing this flaw as NOTABUG.
