OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483. OpenSSH 4.6 y anteriores, cuando ChallengeResponseAuthentication está habilitado, permite a atacantes remotos determinar la existencia de cuentas de usuario intentando autenticarse mediante S/KEY, lo cual muestra una respuesta diferente si la cuenta de usuario existe, un problema similar a CVE-2001-1483. OpenSSH, when configured to use S/KEY authentication, is prone to a remoteinformation disclosure weakness. • http://lists.grok.org.uk/pipermail/full-disclosure/2007-April/053906.html http://lists.grok.org.uk/pipermail/full-disclosure/2007-April/053951.html http://securityreason.com/securityalert/2631 http://www.osvdb.org/34600 http://www.securityfocus.com/bid/23601 https://exchange.xforce.ibmcloud.com/vulnerabilities/33794 https://security.netapp.com/advisory/ntap-20191107-0003 • CWE-287: Improper Authentication •
