CVSS: 2.6EPSS: 1%CPEs: 2EXPL: 1CVE-2006-5229 – Portable OpenSSH 3.6.1p-PAM/4.1-SuSE - Timing Attack
https://notcve.org/view.php?id=CVE-2006-5229
OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds. OpenSSH portable 4.1 en SUSE Linux, y posiblemente en otras plataformas y versiones, y posiblemente bajo configuraciones limitadas, permite a atacantes remotos determinar nombres de usuario válidos mediante discrepancias de tiempo en las cuales las respuestas tardan más para nombres de usuario válidos que para los inválidos, como ha sido demostrado por sshtime. NOTA: a fecha de 14/10/2006, parece que este problema depende del uso de contraseñas configuradas manualmente que provoca retrasos procesando /etc/shadow debido a un incremento en el número de rondas. • https://www.exploit-db.com/exploits/3303 http://secunia.com/advisories/25979 http://www.osvdb.org/32721 http://www.securityfocus.com/archive/1/448025/100/0/threaded http://www.securityfocus.com/archive/1/448108/100/0/threaded http://www.securityfocus.com/archive/1/448156/100/0/threaded http://www.securityfocus.com/archive/1/448702/100/0/threaded http://www.securityfocus.com/bid/20418 http://www.sybsecurity.com/hack-proventia-1.pdf http://www.vupen.com/english • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
