[原文]The default installation of SAP R/3 46C/D allows remote attackers to bypass account locking by using the RFC API instead of the SAPGUI to conduct a brute force password guessing attack, which does not lock out the account like the SAPGUI does.


[CNNVD]SAP R/3 sapinfo RFC API帐户锁定漏洞(CNNVD-200404-029)

        
        SAP R/3是一个基于客户/服务机结构和开放系统的,集成的企业资源计划系统。
        SAP R/3对多次登录尝试没有正确锁定帐户,远程攻击者可以利用这个漏洞对帐户进行暴力猜解。
        默认安装下,SAP R/3会在三此错误登录尝试后SAPGUI会杀掉GUI,在4次SAPGUI崩溃(4*3 =3D 12次尝试)后,测试的帐户就会琐定(在SAPR3.USR02 UFLAG=3D128)。但是攻击者如果使用SDK RFC的sapinfo工具进行密码验证操作,可以多次进行连接而SAP不锁定用户帐户,这可导致攻击者对已知用户进行暴力猜测。

SAP R/3 46C/D Brute Force Logins Bypass Account Locking
Remote / Network Access Authentication Management
Loss of Confidentiality
Exploit Public

- 漏洞描述

SAP server-side Remote Function Call (aka RFC) API contains a flaw that may allow a malicious user to undertake a brute-force attack against accounts without inducing a lock-out. The issue is due to insufficient checking placed on the Remote Function Call API which can be used in place of the GUI for authentication. It is possible that the flaw may allow account compromise, resulting in a loss of confidentiality.

- 漏洞讨论

SAP R/3 may not lock a user account after numerous attempts to login fail. On a default installation, SAP R/3 is designed to lock out accounts that fail to properly authenticate after a set number of times.

An attacker can use the sapinfo utility to attempt to verify a password for a victim user. Due to the use of the sapinfo utility, SAP does not lock out the user account. This may provide the attacker with a greater chance of success for determining the victim user's password.

- 漏洞利用

There is no exploit required.
