CVE-1999-1231 describes an information disclosure vulnerability in ssh 2.0.12 and potentially other versions of ssh2. This flaw allows remote attackers to enumerate valid usernames on a server. The vulnerability arises because the SSH server responds differently to password attempts for valid versus invalid usernames. The CVSS score of 5.0 (Medium) indicates a network-based attack with low complexity, requiring no authentication, and resulting in partial confidentiality impact (information disclosure). The FAUCET Risk Score is 17/100, suggesting a relatively low overall risk. There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. The CVE has received no community discussion or media coverage, indicating a lack of widespread attention.
