[原文]Directory traversal vulnerability in the vfs_getvfssw function in Solaris 2.6, 7, 8, and 9 allows local users to load arbitrary kernel modules via crafted (1) mount or (2) sysfs system calls. NOTE: this might be the same issue as CVE-2004-1767, but there are insufficient details to be sure.


[CNNVD]Sun Solaris vfs_getvfssw函数本地权限提升漏洞(CNNVD-200412-819)

        Solaris 2.6,7,8,以及9版本的vfs_getvfssw函数存在目录遍历漏洞。本地用户可以借助畸形的(1)安装,或者(2)sysfs系统调用装载任意内核模块。

Sun Solaris 2.6/7.0/8/9 vfs_getvfssw function Local Privilege Escalation Vulnerability (EDBID:23874)

It has been reported that Sun Solaris may be prone to a local privilege escalation vulnerability that may allow an attacker to gain root access to a vulnerable system. The issue exists due to insufficient sanitization of user-supplied data via the vfs_getvfssw() function in the Solaris kernel. An attacker can load a user-specified kernel module by using directory traversal sequences and employing the mount() or sysfs() system calls.
