[原文]sdbstarter in SAP MaxDB 7.6.0.37, and possibly other versions, allows local users to execute arbitrary commands by using unspecified environment variables to modify configuration settings.


[CNNVD]SAP MaxDB sdbstarter环境变量本地权限提升漏洞(CNNVD-200803-176)

        MaxDB是SAP应用中广泛使用的数据库管理系统。


        MaxDB所发布的sdbstarter程序在处理某些环境变量时存在漏洞,本地攻击者可能利用此漏洞提升自己的权限。


        这些环境变量用于指定各种MaxDB组件所使用的配置设置。由于sdbstarter程序使用了这些设置,因此本地攻击者可能以root用户权限执行任意指令。如果要利用这个漏洞,攻击者必须能够执行sdbstarter程序,默认下这要求攻击者为sdba组成员。

iDefense Security Advisory 03.10.08 – Local exploitation of a design error in the “sdbstarter” program, as distributed with SAP AG's MaxDB, could allow attackers to elevate privileges to root. iDefense has confirmed the existence of this vulnerability in SAP AG's MaxDB version 7.6.0.37 on both Linux and Solaris. Other versions for Unix-like systems are suspected to be vulnerable. Windows releases do not include the “sdbstarter” program.

I. BACKGROUND

SAP's MaxDB is a database software product. MaxDB was released as open
source from version 7.5 up to version 7.6.00. Later versions are no
longer open source but are available for download from the SAP SDN
website (sdn.sap.com) as a community edition with free community
support for public use beyond the scope of SAP applications. The
"sdbstarter" program is set-uid root and installed by default. For more
information, visit the product's website at the following URL.

https://www.sdn.sap.com/irj/sdn/maxdb

II. DESCRIPTION

Local exploitation of a design error in the "sdbstarter" program, as
distributed with SAP AG's MaxDB, could allow attackers to elevate
privileges to root.

This vulnerability exists due to a design error in the handling of
certain environment variables. These variables are used to specify the
configuration settings to be used by various MaxDB components. Since
the "sdbstarter" program honors these settings, an attacker can execute
arbitrary code with root privileges.

III. ANALYSIS

Exploitation allows an attacker to execute arbitrary code with root
privileges. To exploit this vulnerability, an attacker must be able to
execute the "sdbstarter" program. In a default installation, this
requires that the attacker be a member of the "sdba" group.

It is important to note that this vulnerability is not architecture
dependent. This vulnerability is trivially exploitable on any
Unix-based SAP MaxDB installation.

IV. DETECTION

iDefense has confirmed the existence of this vulnerability in SAP AG's
MaxDB version 7.6.0.37 on both Linux and Solaris. Other versions for
Unix-like systems are suspected to be vulnerable. Windows releases do
not include the "sdbstarter" program.

V. WORKAROUND

iDefense is currently unaware of any effective workaround for this
issue.

VI. VENDOR RESPONSE

SAP AG has addressed this vulnerability by releasing a new version of
MaxDB. For more information, consult SAP note 1140135.

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CVE-2008-0306 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org/), which standardizes names for
security problems.

VIII. DISCLOSURE TIMELINE

12/05/2007  Initial vendor notification
12/06/2007  Initial vendor response
03/10/2008  Coordinated public disclosure

IX. CREDIT

This vulnerability was discovered by Joshua J. Drake of VeriSign
