[原文]Rule Set Based Access Control (RSBAC) 1.2.2 through 1.2.3 allows access to sys_creat, sys_open, and sys_mknod inside jails, which could allow local users to gain elevated privileges.


[CNNVD]RSBAC Jail SUID和SGID文件建立漏洞(CNNVD-200408-094)

        
        RSBAC是一款Linux内核基于规则的访问控制安全增强系统。
        RSBAC的Jail进程不正确允许文件以SUID和SGID属性建立,本地攻击者可以利用这个漏洞在Jail环境中提升权限。
        在Jail环境下,攻击者可以利用程序使用sys_creat, sys_open和sys_mknod函数建立suid和sgid文件,这可导致攻击者提升权限,然后对系统进行进一步攻击。

- 受影响的程序版本

RSBAC RSBAC 1.2.3
RSBAC RSBAC 1.2.2
Gentoo Linux 1.4

- 漏洞讨论

The process jail feature of RSBAC reportedly improperly allows files to be created with SUID and SGID attributes.

These files can then be used to escalate the privileges inside the jail. This may allow for further attacks and possible system compromises.

Versions 1.2.2 and 1.2.3 are reported to be vulnerable to this issue. A patch has been released by the vendor.
