S/Key和OPIE数据库漏洞

在使用S/Key或OPIE认证的服务器上存在一个安全漏洞。这个漏洞允许本地用户获得对S/Key或OPIE数据库的访问权。 S/Key是使用一次性口令技术的认证机制。系统管理员可以进行配置，使用户能够通过S/Key认证访问使用login8的任何服务，如Telnet和FTP。制定认证类型的配置文件是/etc/login.conf。 为了配置一个用户能够使用S/Key，管理员或该用户（如果程序是suid root）首先必须使用skeyinit（或keyinit）程序。这个程序初始化S/Key数据库（/etc/skeykeys）中的用户入口项。这个数据库文件包含输入S/Key口令时需要比较的信息...

OPIE -- arbitrary password change

Problem Description The opiepasswd1 program uses getlogin2 to identify the user calling opiepasswd1. In some circumstances getlogin2 will return "root" even when running as an unprivileged user. This causes opiepasswd1 to allow an unpriviled user to configure OPIE authentication for the root user...
